Problems solved by technology

[0002] During the development of oilfields, generally in low-yield areas and when the underground energy is insufficient, oil extraction is carried out through pumping units, which can obtain higher crude oil production, but for heavy oil and high pour point oil reservoirs, there are problems Numerous cluster wells are concentrated in one location, and are equipped with several pumping units to perform oil production at the same time. During the production process, a large amount of electric energy is consumed to drive these pumping units to operate. The use of pumping units not only increases the area occupied The area is a waste of electric energy, and it is very inconvenient to manage. It needs frequent maintenance, which undoubtedly increases the production cost and wastes manpower and material resources.
In addition, in order to increase the production of oil wells in thin oil wells, some of the existing technologies have adopted hydraulic piston pumps to increase the production of single wells through the method of large pump displacement, but for heavy oil wells, due to the high viscosity of crude oil, low production capacity and steam injection Due to the influence of high temperature, this method cannot be used

Embodiment 1

[0020] The voltage regulating cabinet 1 is a rectangular iron cabinet with an electronic circuit power supply motor 2, which is connected to the motor 2 through wires, and the high-pressure pump 3 is the power source. The upper piston 23 and the lower piston 28 in the hydraulic pump move, and the liquid flows through the high-pressure pipeline 4; the pump inlet pipeline 7 is respectively connected with the high-temperature heating furnace 5, the filtering device 8, and the crude oil filter 9, and the high-temperature heating furnace 5 is a wellhead The water jacket heating furnace is connected to the high-pressure pipeline 4 through the pipeline connected by the inner coil, which can send the high-temperature liquid in the pipeline into the well. The crude oil filter 9 is cylindrical in shape and has a metal filter inside to filter Due to the sand particles carried in the crude oil, the high-pressure pipeline 4 is connected to the wellhead 14 through the surface high-pressure p...

Embodiment 2

[0022] The downhole hydraulic oil extraction pump 49 mainly includes an upper pump barrel 43, a lower pump barrel 39, an upper piston 23, a lower piston 28, a piston pull rod 27, an upper valve ball 19, a lower valve ball 20, an upper oil inlet valve ball 30, a lower inlet valve ball Oil valve ball 32, oil inlet channel 33 (the channel acts as the inlet of crude oil in the well), and high-pressure power fluid nozzle nozzle 18, crude oil pump outlet 21 on the upper and lower pump barrel walls, crude oil pump inlet 22, and liquid inlet reversing A valve 25, a crude oil suction port 29, a power fluid inlet 48, and a power fluid discharge port 41 are formed. The nozzle 18 of the high-pressure power fluid nozzle is a conical cylindrical nozzle with 4 circular holes of the same diameter, through which the high-pressure liquid flow is injected into the downhole hydraulic pump to force the piston to move up and down.

Embodiment 3

[0024] When the present invention works, the fluid medium is sucked into the pump by the surface high-pressure pump 3 and after being pressurized and heated, it is sent into the downhole hydraulic oil production pump 49 in the well through the hollow sucker rod 51 in the wellhead 14.

[0025] The downhole hydraulic oil extraction pump is composed of a two-way hydraulic cylinder pump barrel, an upper pump barrel 43 and a lower pump barrel 39. When working, the hydraulic pressure is used to push the upper piston 23 and the lower piston 28 in the hydraulic cylinder to move up and down, and the This creates a vacuum pressure in the cylinder, so that the piston of the pump body performs continuous and alternate work of suction and discharge respectively, and completes the suction and discharge actions under the action of the liquid inlet reversing valve 25. When it is raised to the ground, at this time, part of the well fluid is input into the pump station, and the other part of the...

Abstract

The present invention is one kind of multifunctional hydraulic oil extracting apparatus for nonflowing well without oil pumping unit. The multifunctional hydraulic oil extracting apparatus consists of a voltage regulating cabinet, a motor, a high pressure pump, a high pressure pipeline, a high temperature heating furnace and a filter. Inside the well, there are casing, oil pipe, polished rod sealer, hollow sucker rod, and hydraulic oil extracting pump. High pressure liquid is provided from ground to well for the hydraulic oil extracting pump to operate continuously to make liquid inside the well to flow to ground. The apparatus has integrated functions of extracting oil, electrically heating, relieving oil and exhausting sand, and possesses small floor space, low power consumption, low maintenance cost and high oil pumping efficiency, so that it may be used widely in extracting thick oil from horizontal well and cluster wells.
