Abstract

The utility model discloses a highly-efficient fixing double valve ball exhaust oil well pump, comprising an outer body main pipe. An oil pump body is sleeved by the outer body main pipe. The oil pump body is provided with a pump core, an oil bleeder, an upper valve ball seat, a lower valve ball seat and a liquid inlet pipe successively from the top to the bottom. An oil return pipe is sleeved by the liquid inlet pipe, and the upper part of the outer body main pipe is provided with an air outlet. The lower part of the air outlet of the outer body main pipe is provided with a liquid inlet, and the lower part of the liquid inlet pipe is provided with a liquid inlet hole. The highly-efficient fixing double valve ball exhaust oil well pump resolves the problem that petroleum exploitation cannot be normally conducted due to the fact that a valve ball is jacked up.

Description

A kind of efficient fixing two anti-that ball exhaust oil well pumps

Technical field

The utility model belongs to the oil exploration equipment technical field, relates to a kind of efficient fixing two anti-that ball exhaust oil well pumps.

Background technique

When carrying out petroleum production with oil well pump, often can run into have bubble in pump barrel, anti-your ball by jack-up, causes and can't normally recover the oil when running into especially big gas.

Summary of the invention

The purpose of this utility model is to provide a kind of efficient fixing two anti-your ball exhaust oil well pumps, has solved when petroleum production anti-your ball by jack-up and the normal problem of recover petroleum.

The technological scheme that the utility model adopts is, a kind of efficient fixing two anti-that ball exhaust oil well pumps, comprise the ectosome supervisor, be socketed with the oil pump main body in the ectosome supervisor, the oil pump main body is disposed with pump core, oil drainer, upper anti-that ball seat, lower anti-that ball seat and liquid inlet pipe from top to bottom, is socketed with in liquid inlet pipe and returns oil pipe, and ectosome is responsible for top and is had relief opening, have liquid entering hole below ectosome supervisor's relief opening, the bottom of liquid inlet pipe has inlet opening.

The beneficial effects of the utility model are that by upper anti-that ball seat and lower anti-that ball seat are set, when anti-your ball in anti-your ball seat can not be worked by jack-up instantly, upper anti-that ball seat can replace effect and then normal oil recovery of lower anti-that ball seat.

Description of drawings

Fig. 1 is the structural representation of a kind of efficient fixing two anti-your ball exhaust oil well pumps of the utility model.

In figure, 1. ectosome supervisor, 2. oil pump main body, 3. pump core, 4. oil drainer, 5. anti-your ball seat, 6. liquid inlet pipe, 7. return oil pipe, 8. relief opening, 9. liquid entering hole, 10. inlet opening, 11. times anti-your ball seats.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

The utility model provides a kind of efficient fixing two anti-that ball exhaust oil well pumps, as shown in Figure 1, comprise ectosome supervisor 1, be socketed with oil pump main body 2 in ectosome supervisor 1, oil pump main body 2 is disposed with pump core 3, oil drainer 4, upper anti-that ball seat 5, lower anti-that ball seat 11 and liquid inlet pipe 6 from top to bottom, is socketed with in liquid inlet pipe 6 and returns oil pipe 7, and ectosome is responsible for 1 top and is had relief opening 8, ectosome supervisor 1 relief opening 8 belows have liquid entering hole 9, and the bottom of liquid inlet pipe 6 has inlet opening 10.

Liquid entering hole 9 in oil well pump of the present utility model is higher than the bottom of pump core 3, when oil well pump is worked, form the space between ectosome supervisor 1 and oil pump main body 2, so during liquid entering hole 9 feed liquor, the downward sedimentation of liquid, gas is along the upwards diffusion of ectosome supervisor 1 inwall, and then a large amount of gas is discharged from by relief opening 8.During as especially big gas, anti-your ball of existing apparatus is not fallen by jack-up, can not normally recover the oil, by the utility model oil well pump, upper anti-that ball seat 5 and lower anti-that ball seat 11 are set, when anti-your ball in anti-your ball seat 11 can not be worked by jack-up instantly, upper anti-your ball seat 5 can replace effect and then normal oil recovery of lower anti-your ball seat 11.

Claims
