Abstract
The utility model relates to an oil-water separation device, in particular to a downhole oil-water separation device. According to the technical scheme, the downhole oil-water separation device comprises a motor, a motor protector, an electric submersible pump, a cyclone separator, a one-way valve, a packer and an oil pipe. The motor, the electric submersible pump, the cyclone separator, the one-way valve and the packer are respectively arranged in the oil pipe, the motor is connected with the electric submersible pump which is connected with the cyclone separator, the cyclone separator is connected with the lower portion of the packer through the one-way valve, and an outlet of the cyclone separator is connected to the oil pipe on the upper portion of the motor through a connecting pipe. The downhole oil-water separation device has the advantages of sharply reducing water contained in the ground, increasing oil production, reducing oil extraction cost of oil fields rich in water, improving comprehensive benefits of the oil fields and oil extraction efficiency, and reducing equipment investment, operating cost and production cost.
Description
Technical field
The utility model relates to a kind of oily-water seperating equipment, particularly a kind of downhole oil-water separation device.
Background technology
Along with the oil field enters after the middle high water-cut stage, expose a series of contradictions in the field produces, mainly comprise oil well because of Water-Content Rise near the economic exploitation limit, cause prematurely to stop production, cause recovery ratio to descend; High output of oilwell water causes the water treatment scale to increase, and treatment facility drops into and operating cost constantly increases; The simultaneously leakage in the output water treatment procedure and discharging causes more and more outstanding environmental protection pressure.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of downhole oil-water separation device is provided, and improves the oil field comprehensive benefit, and oil recovery efficiency improves.
Its technical scheme is: comprise motor, motor protecter, electric submersible pump, cyclone separator, one way valve, packer, oil pipe; oil pipe inside is respectively equipped with motor, electric submersible pump, cyclone separator, one way valve, packer; motor connects electric submersible pump; electric submersible pump connects cyclone separator; described cyclone separator is by the bottom of one way valve connection packer, and the outlet of cyclone separator is connected in the oil pipe on motor top by tube connector.
Above-mentioned outside motor is provided with motor protecter.
The beneficial effects of the utility model are: decrease ground moisture, increased oil production, reduce the cost for oil production of high water cut oil field, improve the oil field comprehensive benefit, oil recovery efficiency improves, and has reduced equipment investment and operating cost, has reduced cost of production.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Among the upper figure: motor 1, motor protecter 2, electric submersible pump 3, cyclone separator 4, one way valve 5, packer 6, oil pipe 7, tube connector 8.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises motor 1, motor protecter 2, electric submersible pump 3, cyclone separator 4, one way valve 5, packer 6, oil pipe 7, oil pipe 7 inside are respectively equipped with motor 1, electric submersible pump 3, cyclone separator 4, one way valve 5, packer 6, motor 1 connects electric submersible pump 3, electric submersible pump 3 connects cyclone separator 4, described cyclone separator 4 is by the bottom of one way valve 5 connection packers 6, and the outlet of cyclone separator is connected in the oil pipe on motor top by tube connector 8; Described motor 1 outside is provided with motor protecter 2, and the longer service life of protection motor reduces fault rate.
Use this device decrease ground moisture, increased oil production, reduce the cost for oil production of high water cut oil field, improve the oil field comprehensive benefit, oil recovery efficiency improves, and has reduced equipment investment and operating cost, has reduced cost of production.
