Up to several dozen injection wells are connected to pumping stations, called cluster pumping stations (CPS). The greatest development was received by cluster pumping stations of block design. There are block cluster pumping stations (BKNS) based on centrifugal pumps 1 2 3 5 6 4 7 6 5 4 3 2 1 a b CNS-180 and CNS-500. The composition of the BKNS depending on the number of pumps is given in Table 1.4.1.

The BKNS includes two types of pumping units: NB-1 (outer pumping unit) and NB-2 - middle. Block NB-1 is mandatory regardless of the number of pumping units in the BKNS. The difference between these blocks is in the execution of their shelter.
The intake line of the pumping unit is equipped with a strainer and a manual valve type ZKL2, the discharge line is equipped with a check valve and an electric valve type B-403.
The pressure manifold block (BG), designed to account for and distribute the TJ coming from the pump through pressure pipelines, is placed in a separate all-metal box at a distance of at least 10 m from the other blocks. Includes distribution manifold, backwash manifold, control station, flow meter with orifice, shut-off valve, fan, maintenance platform, electric furnace.
Rice. 1.4.2 - Typical technological scheme of BKNS
A promising direction is the use of hydraulic modular pumps with “absolute” flow control.
Electric wire and cables are laid in metal boxes, steel pipes, flexible metal hoses. In the BA, electrical wires (tightened into bundles) and cables are laid in trays under the flooring, access to which is through hatches.
The station works as follows. Process water is supplied through the suction pipeline to the inlet of the centrifugal pump TsNS-180. From the pump, through a pressure pipeline, water is supplied to the BG, where it is distributed to eight, five or four water pressure conduits (depending on the type of BG) and then fed to injection wells.
There is a special collector for the discharge of water from the conduits during the repair of the BG. Pump units with pumps TsNS 180-1900 and TsNS 180-1422 are equipped with individual oil systems that provide forced oil supply for lubrication and cooling of the pump and motor bearings.
The water cooling system provides:
Oil cooling during forced lubrication of bearings of the NB pumping unit;
Cooling of ND bearings with pump TsNS-1050;
Supply of water for cooling and locking the seals of the end seals of the TsNS-180 pumps in the event of a pressure drop in the suction pipe of the pump to 0.1 MPa, as well as cooling of electric motors with SCW.
Waste water is periodically pumped from the reservoir by the main pumps BD TsNSK-60/254 to the inlet of the TsNS-180 pumps.
The BA is equipped with equipment that provides start-up, control of the main parameters and operation of the station, power distribution equipment, engine control panels, heating and drainage pumps. Measurement, recording of pressure and water flow. entering the injection wells is produced by flow meters located on each BG conduit.
As the main option, we will consider a pumping unit with forced lubrication of the bearings of the pumping unit ON (the pressure at the buyout of the pumps is above 10 MPa).
The NB has:
Pumping unit ON, consisting of a pump type TsNS-180 and an electric motor;
Oil installation and pipelines of the lubrication system with fittings;
Pipelines and fittings for process water;
Pipelines and fittings of the cooling system;
Pipelines for backwater and cooling of pump stuffing boxes;
Drainage pipelines;
Push-button control post for oil plant,
Push-button control post for electric gate valve;
Box and pipes of electrical wiring,
Danger button;
Manometer column;
The installed equipment is mounted and fixed on the sledges and enclosing structures of the unit.
The centrifugal sectional pump TsNS-180 has a rated capacity of 180 m 3 / h at a design (nominal) pressure at the pump outlet. It is allowed to change the water flow from 50 to 180 m 3 /h at a water density equal to 1000-1001 kg/m 3 .
To protect the flowing part of the pump from large mechanical impurities, a strainer is installed in the suction pipe.
Two types of electric motors are used to drive the pump - synchronous and asynchronous. Cooling of air in engines with CCW is carried out by fresh water. In motors with RCV, the stator windings are cooled by air from the engine room.
Oil system ON consists of an oil tank with a capacity of 0.6 m 3 , a gear oil pump with an electric drive with a capacity of 2.1 m 3 /h and a pressure of 0.27 MPa, an oil cooler with filters and a pipeline system with shutoff valves.
A wedge gate valve of the ZKL2 type and a strainer are installed on the process water suction pipeline. A non-return valve and an electric drive valve V-407E are installed on the pressure pipeline. An air bleed valve is installed at the top of the pressure pipeline.
The pipelines of the cooling system are intended for supplying cooling water to the oil cooler and air coolers of engines with SCW. Water is supplied from the cooling system to lock and cool the end stuffing box seals of the pump when the pressure drops below 0.1 MPa in the pump inlet pipe.
When the pump operates with a pressure in the inlet pipe from 0.6 to 3.0 MPa, the stuffing boxes are unloaded and water is drained through the slotted seals of the pump into a non-pressure tank. Water is drained from the chamber of the hydraulic foot of the pump into the suction pipeline. Drainage from the end seals of the pump is made into a drainage tank installed in the DU.
Local control of technological and operational parameters of the operation of pumping units, setting of alarm sensors are carried out according to pressure gauges and readings of the ammeter of the STD type engine excitation circuit.
After starting with the "start" button from the control panel installed in the BA, the oil pump is turned on, and when the pressure at the end of the oil line reaches 0.05 ... 0.1 MPa, the main pump starts. the electric valve on the discharge line opens.After opening the valve within 60s, the pump enters the steady state operation.
In the pumping unit with a vibration isolation system for pumping units, the pumping unit with the frame is mounted on rubber-metal shock absorbers attached to the sled. Expansion joints are installed on the suction and pressure pipelines of the pump, and rubber sleeves are installed on the pipelines for supplying lubricants and stuffing boxes.
During operation of the station, due to shock absorbers and elastic compensating inserts on pipelines, vibration transmission from the pumping unit to pipelines, supporting structures, block bases and foundations is reduced, and noise transmission is also reduced.
Installed in the database:
2 pumping units with TsNSK-60/264 pumps;
Drainage tank;
2 self-priming pumps 1STsV-1.5M;
4 units of PET-4 ovens;
Protective electrical wiring boxes;
Pipelines and fittings for process water.
Pumps 1STs8-1.5M are designed for pumping water from a drainage tank into a wastewater tank. TsNSK-60/264 type pumps are used for pumping water from the sewage tank into the NB suction pipeline.
1 pump is standby. The pressure manifold block (BG) is used to distribute process water to the wells of the reservoir pressure maintenance system. Six types of pressure manifold block have been developed depending on the number of conduits and the type of water flow measurement device.
BG has:
Block of pipelines;
Flow measurement device;
Service area;
Elements of ventilation and heating,
Control cabinet;
Push-button ventilation control post.
The piping block consists of a pressure manifold with control valves, high-pressure conduits, a discharge manifold, valves and a flow measurement device. The change in the process water flow is carried out by control valves installed on the pressure manifold.
Depending on the number of conduits, the blocks of pressure manifolds are divided into 8-, 5- and 4-water conduits. 5- and 4-way pressure manifold blocks can be supplied separately from the station. According to the type of water flow measurement device, the comb blocks are supplied with: a narrowing device complete with a shield of differential pressure gauges; equipment Electron-2M; flow sensor DRK 1-100-50-5.
When installing the Electron-2M equipment and the DRK 1-100-50-5 flow sensor, the primary devices are installed directly on the pressure pipelines in the BG, and the secondary devices are installed on racks in a separate instrument block (OP). To heat the unit, 3 oil-filled furnaces with a power of 2 kW each with temperature control are installed. Ventilation is carried out by taking air through an air duct located on the floor of the unit, by an axial fan type B-06-300 No. 5H1C, installed on the side panel.

Technical characteristics of wellhead fittings for injection wells are given in Table. 10.6.1.
Rice. 10.6.1. - Injection well design
Table 10.6.1
Technical characteristics of wellhead fittings for injection wells
The injection fittings are tied with the injection line of the well (Fig. 10.6.1).
The following requirements are imposed on the design of injection wells:
1. The injection wellhead equipment must comply with the design, the development of which must take into account the composition, physical and chemical properties of the injected agent and the maximum expected injection pressures;
2. injection wells, regardless of the physical and chemical properties of the injected agent, must be equipped with a tubing string and, if necessary, a packer device that provides protection and isolation of the production string from the impact of the injected agent on it;
3. To prevent freezing of water in the well fittings and the injection system during shutdowns, it is necessary to provide for the complete removal of water from the fittings and the working agent supply system and filling the specified equipment with an antifreeze liquid.
The principle of operation of the injection well
Water from the VRB (VRG) is supplied through the injection line of the well and the wellhead tee to the tubing, and through them enters the reservoir. The choice of parameters of the tubing of injection wells is carried out based on the conditions of mechanical strength and permissible pressure losses during the injection of TJ. The flow rate of the process fluid injected into the injection well is regulated by a fitting (5) or a flow regulator (see Fig. 10.6.2). To control the water injection process, the well fittings are equipped with high pressure valves (9 and 12).

Maintenance of injection wells
Maintenance of injection wells is carried out by operators to maintain working pressure. Injection wells are serviced daily.
When servicing injection wells, the following are controlled:
Working (linear) and wellhead pressure;
Operation of instrumentation and equipment;
Condition of valves and flange connections;
Status of protective devices;
Condition (presence) of the fitting or control device.
Repair of injection wells
The need for repair of the injection well is determined by the geological and technological services of the pressure maintenance shop based on the results of the research. The need for repair of ground equipment is determined by the foreman of the TsPPD and confirmed by the head of the shop.
The repair of injection wells is carried out by the workover and overhaul crews. The underground (current) well workover team replaces the valves, and the overhaul team performs repair and insulation work, eliminates leaks in the production string, eliminates various kinds of accidents, puts wells into operation and works to increase well injectivity. Repair of injection wells is carried out on the basis of a work plan, which indicates the type of repair, the procedure for killing the well and performing work, equipment to be lowered, etc. The well must first be prepared for repair.
Preparation of wells for workover is the responsibility of the operator to maintain reservoir pressure, and the following scope of work must be performed:
Access roads to the well are checked, if necessary, the road is backfilled;
A site for the repair team is being prepared (planned), in winter it is cleared of snow with the help of special equipment. The size of the site must be at least 40x40m.
Well injection fittings are being prepared. Flange connections on injection fittings must have a complete set of fasteners, gate valves and high-pressure valves must be in good order, no leakage of the working agent through flange connections is allowed.
The secant and pipe valves of the injection fittings are closed, the pressure in the injection line of the well is released to atmospheric pressure.
Conclusion to the regime and the study of injection wells
The purpose of bringing the injection well to the mode is to bring the operating pressure and fluid flow in line with the mode parameters. The output of the well to the mode is carried out on the basis of the technological mode of operation of the injection wells, approved by the chief engineer of the enterprise.
The task of the operator to maintain reservoir pressure when bringing the well to production is to control the working pressure and the amount of injected working agent.
The output to the mode is carried out as follows:
The RPM operator daily measures the pressure and flow of the working agent. After starting the well, during the first 2-3 days at a relatively low injection pressure, a large consumption of the working agent is observed, this is due to a decrease in pressure in the bottomhole zone of the well after repair;
After stabilization of the working pressure, the well operation mode is regulated. By selecting the diameter of the choke or flow section of the control device, the working pressure and flow rate along the well are brought into line with the regime indicators.
The well is considered to be brought to the regime if 3 measurements of the flow rate of the working agent in the well during the day correspond to the regime indicators at a constant injection pressure.
During the operation of wells, downhole and surface instruments should be used to constantly monitor injectivity, injection pressure and coverage of reservoirs by waterflooding in thickness. Reservoir pressure, formation filtration parameters and well injectivity factors are determined by testing wells using methods of bottomhole pressure drop and steady test injections.
The interaction of wells and the ways of movement of the injected water through the reservoir are studied by the dynamics of pressure in different sections of the reservoir, the results of studies by the method of interference testing, geophysical methods, the addition of indicators to the injected water. Evaluation of the effectiveness of measures to regulate water injection along the section is carried out using downhole flowmeters, the method of radioactive isotopes or highly sensitive thermometers.
The frequency and scope of research work in injection wells is established by the enterprise in accordance with the approved mandatory set of field geophysical and hydrodynamic studies, taking into account the requirements of the technological design document for development.

Coordination of railway training programs
The requirements for professions that determine professional standards and the development of technologies are constantly changing, in connection with this, the process of changing, adjusting and updating curricula, in particular for railway professions, is constantly going on. Last week, we received training programs agreed and approved by the Ministry of Transport and the Federal Agency for Railway Transport for professions:
Learning to operate a railway crane
Last week, the theoretical training of a railway crane operator was completed. It was the railway crane operators who studied, taking into account all the specifics: shunting, signaling and safety rules on the railway ... The course focused on cranes KDE-251 and KZhDE-25, as well as EDK-1000/2 with increased load capacity up to 125 tons.
Next week, students will go to our training ground, where they will put into practice the theoretical knowledge gained under the guidance of experienced instructors.
Introduction to oil and gas production
Where does oil come from? How is it mined and what is it processed into? How are drilling rigs built, drilled and completed wells?
All this was discussed at the course "Introduction to oil and gas production", which was held by specialists from the oil and gas division of PromResurs last week.
Although the course has ended, we will be happy to repeat it for you.
The course will be useful to you if:
We studied: Training of galvanizers
There are a little more people who have mastered a qualified specialty, Hooray!
Our specialists conducted another training for the employees of the electroplating shop with the organization of theoretical and practical classes. In the course of practical exercises, work was carried out to cover parts of complex shapes.
Now electroplating will be able to independently perform the declared work, and the company will not spend invaluable time on their training in the process of working on productive parts and will reduce the level of defects in their production.
We are waiting for everyone who has not completed the training yet!
Recruitment of the Railway Crane Operator group in July
Friends, at the end of July, training in the profession of "Railway Crane Operator" will begin.
Training will consist of 2 parts: Theoretical and Practical.
The theoretical part is held from July 31 to August 18, 2017. The training will cover topics such as crane construction, operation, loading and unloading, railway signaling and the basics of maneuvering.

Thank you, Konstantin Lyubnardovich! It also seems to me that the time has come to step aside from politics and engage in real oil business .....

Dear organizers, I want to remind you that this year June 21 is the anniversary of the discovery of the first industrial oil in Shaim. The discoverers are Rovnin, Ervie, Shalavin, Urusov, and other interesting people. I want to note that Salmanov has NOTHING to do with this discovery, even indirectly. My phone. 89032705910. I can send you a 1964 documentary. The way to the first oil. Sverdlovsk Film Studio. Not on the films, but you can find it on the Internet. I also have the film Chief Geologist. It was shown on UGRA TV.

The words are beautiful and correct, but where are the deeds? Only I know how to conduct bottom seismic surveys on the shelf in a robotic way; only my design of an automated bottom rig can drill wells without people (for more details, see Aviagr LiveJournal). Hundreds of other inventions - and all of them are not in demand by VINKS, who spend money on "instructions for eating sausage" - the so-called. "digitization". But with numbers, as if with the word of God, you can’t drill a well, you can’t pump out oil, you can’t free it from water and mechanical impurities - you need IRON! Efficient, reliable and inexpensive. Words won't help matters...

I am outraged that the nets for sorting plastic have been removed. Apparently Mr. Moore is very worried about his position and is afraid to contact the owners of the plant (which is inactive). And our courts all sing in the tune of the leaders of the region.
For me personally, sorting garbage is not difficult. There was even some pride that Tyumen began to approach civilized countries.
I don't need to introduce myself on this site.
I fully agree with Oleg Alexandrovich Anisimov.
I can only add from myself, and what other message could be expected from the director of the "CENTER FOR ENVIRONMENTAL INVESTMENTS" - only this: "... there will be huge damage, and huge investments in the environment will be required ...".

Dear Vladimir Alexandrovich, I sincerely congratulate you and your wonderful family on the New Year! Happiness to you for all the years! So appointed by fate, all doubts - down! "Rejoice in everything!" - Wise men say so. I ask you, dear Vladimir Alexandrovich, to call me as soon as possible. My phone is 8-913-800-95-98.

Field them. Dinkov "separated" from Rusanovsky, discovered 30 years ago, previously considered one. The total reserves turned out to be less than earlier in a single Rusanovskoye. Nyarmeyskoye was also a little disappointing. At least 150 were waiting here. Same with many other discoveries

The author is very cautious in his analysis of Russian reality in relation to the Paris Agreement.
There are not 4 such groups in Russia, but much more. One of the main among them is Gazprom and other oil and gas companies. Along with those listed in the article, all these groups with "open beaks" are waiting for external "carbon credits" under Article 6 of the Paris Agreement, as was the case under Article 6 of the Kyoto Protocol. All these groups have tasted offshore participation in the gray scheme of selling Russian emission rights (in the absence of a law on the procedure for the circulation of these rights in Russia) for a total amount of over 2.5 billion US dollars. But if, under the Kyoto Protocol, Russia had the right to veto its entry into force, allowing it to be sold, then under the Paris Agreement (PS), Russia does not have such opportunities. Moreover, developing countries, including China, India, Brazil, simply will not allow Russia to make money on its participation in the PS, which is confirmed by the results of the 25th Conference of the Parties to the UNFCCC in Madrid.
The exception will be Gazprom and Rosenergoatom, which, by exporting their products to other countries, can earn due to the presence of carbon taxes in these countries. But it seems that the Russian budget and economy will not see these revenues, as it was with the participation of Gazprom's subsidiaries in the "carbon market" of the EU and other countries...
