Abstract
The utility model discloses a vertical tandem multi-stage electric pump for water injection. The upper part of the electric pump for water injection is provided with a submersible motor covered by a fairwater, the motor is connected with the base of a Christmas tree via a spacer flange, the shaft of the motor is connected with the shaft of pumps, the pumps are hung to mandrel hangers, and the pumps are connected in series for pumping via hundreds of impellers. Normal pressure water is led to the inlet of the electric pump, the pressure of the outlet of the electric pump can be 250 kg / cm +[2]. The lower parts of the pumps are provided with check valves for preventing high pressure water flowing back when the motor stops. The vertical tandem multi-stage electric pump for water injection has large outlet pressure, long service life of machine unit, convenient maintenance, on-site installation, on-site water injection and random movement, and the vertical tandem multi-stage electric pump for water injection can be connected in parallel for meeting the requirements of large discharge.
Description
The utility model is about water injection equipment, and the model utility of the multistage water filling electric pump of particularly vertical serial connection is applicable to oil-field flooding.It is cut down and is formed by motor, air guide sleeve, counter flange, production tree base, tubing hanger, pump, single current.
At present, domestic have a kind of general water injection equipment, and promptly horizontal type multi-stage pump can be used for oil-field flooding.This pump is made up of seven grades of impeller serials, and by Asynchronous Motor Driving, single-machine capacity is 800 kilowatts, and water at atmospheric pressure is quoted in the ingress of this pump, and outlet pressure can reach 150 kilograms per centimeter
2But this pump needs to use in pump house, can not arbitrarily move, and noise is big in the pump house, temperature is high, and the other noise of machine reaches more than 90 decibels, and summer, room temperature reached more than 40 ℃, and this pump generally uses 5000 hours in addition just needs to shut down overhaul, changes impeller and other easily damaged parts.
In addition, there is a kind of water injection equipment in the U.S., does water injection pump usefulness with oil-immersed pump, drives with oil-submersible motor, and pump adopts vertical serial connection form, and pump is on motor, and its outlet pressure can reach 250 kilograms per centimeter
2More than.But inlet uses high pressure water (150 kilograms per centimeter
2), by the oil-immersed pump supercharging, can make outlet pressure reach 250 kilograms per centimeter
2, this electric pump motor efficient is low, costs an arm and a leg, and needs complete machine to propose during maintenance, uses inconvenience.
Task of the present utility model is to provide a kind of economy, the multistage water filling electric pump of vertical easily serial connection, and when using it, water at atmospheric pressure is introduced in the ingress, and outlet pressure just can reach 250 kilograms per centimeter quickly
2The water injection pump that is provided can be installed on the spot, water filling on the spot, arbitrarily migration.
Solution of the present utility model is: motor adopts submersible type, motor by the air guide sleeve cover, motor is sitting on the production tree base by flange, the axle of motor is connected with the axle of water injection pump, pump is hung on tubing hanger, this water injection pump carries out pumping by hundreds of level impeller serial, and the bottom of pump is equipped with single current and is cut down.
Another technical measures that the utility model is taked are that the axle of motor adopts the internal spline housing to be connected with the axle of water injection pump.
The multistage water filling electric pump of the vertical serial connection that is provided can have two kinds of methods of operation: a kind of is that press water directly injects water injection well: another kind of mode is that this electric pump seat is on the dry-well of a bottom band end socket, high pressure water returns up from dry-well, by production tree base two pass-out mouths, after lock cuts down modulation, press water is input in the other water injection well.
The utility model has bigger use value, is embodied in:
1, water at atmospheric pressure is quoted in the multistage water filling electric pump of this a vertical serial connection ingress, and outlet pressure just can one be issued to 250 kilograms per centimeter
2, can satisfy the water filling needs in most of oil field:
2, pump moves in clear water, can guarantee safe operation 1 year;
3, use this electric pump to need not the construction investment of water flooding pump station, and make operator avoid under high temperature, high noisy condition, working;
4, it is suitable for the block high oil field water injection, and water filling on the spot, arbitrarily migration can be installed on the spot;
5, if any the need of big discharge capacity, this water filling electric pump parallel running of available 5-6 platform can replace a present conventional waterflooding pumping plant;
6, since this electric pump motor more than ground, so maintenance makes things convenient for.
Accompanying drawing has been described embodiment of the present utility model:
Fig. 1 is the multistage water filling electric pump of a vertical serial connection general assembly drawing;
Fig. 2 is the sectional view of motor and pump coupling part.
Submersible motor (1) is connected with production tree base (4) by counter flange (8), motor has adopted major axis to stretch, cable (3) passes air guide sleeve (2) after motor is drawn, and sealed and guided into control cabinet, the motor shaft extension includes spline housing (9) and combines with the spline of pump shaft, counter flange top links to each other with motor, the bottom directly links to each other with the production tree base, the head of water injection pump (6) adopts tubing round thread to be connected with tubing hanger (5), tubing hanger (5) core constitutes the import of pump, and the high pressure lock that need close dead production tree base both sides when direct water filling downwards cuts down and install additional pressure gauge with the monitoring water injection pressure.
Intake pressure is the 1-2 kilograms per centimeter
2Treated clear water flow into from the top of air guide sleeve, be full of whole chamber, the center portion that enters counter flange around motor flows to the import of pump, the pumping by 610 grades of impellers is pressurized to 250 kilograms per centimeter step by step with water
2More than, flow selects different pump types from 200 meters as required
3/ day is to 550 meters
3/ day.Water injection well sleeve pipe (10) external diameter is 5 1/2 English inch, and bearing capacity is 250 kilograms per centimeter
2, provide for oneself by the user.Delivery side of pump is equipped with single current and cuts down (7), in order to avoid high pressure water refluxes when shutting down.
Claims (2)
1, a kind ofly cuts down the multistage water filling electric pump of the vertical serial connection of forming by motor, air guide sleeve, counter flange, production tree base, tubing hanger, pump, single current, it is characterized in that motor adopts submersible type, motor by the air guide sleeve cover, motor is sitting on the production tree base by flange, the axle of motor is connected with the axle of water injection pump, pump is hung on tubing hanger, and the bottom of pump is equipped with single current and is cut down.
2, water filling electric pump according to claim 1, the shaft extension that it is characterized in that motor include spline housing (9) and combine with the spline of the axle of water injection pump.
