Abstract

The utility model discloses an efficient exhaust oil pump with a lengthened oil return tube. The efficient exhaust oil pump comprises an outer main tube. A pump body is nested in the outer main tube. The pump body is provided with a pump core, an oil drain, a valve ball seat and a liquid inlet tube sequentially from top to bottom. An oil return tube is nested in the liquid inlet tube. The upper portion of the outer main tube is provided with an exhaust hole and a first liquid inlet below the exhaust hole. The lower portion of the liquid inlet tube is provided with a second liquid inlet. The lower end of the oil return tube extends into the liquid inlet tube by 10-20m. The problem that failure in effectively discharging the gas in a pump barrel leads to failure of normal oil extraction during oil extraction is solved.

Description

Oil pipe exhaust oil well pump is returned in a kind of efficient lengthening

Technical field

The utility model belongs to the oil exploration equipment technical field, relates to a kind of efficient lengthening and returns oil pipe exhaust oil well pump.

Background technique

When carrying out petroleum production with oil well pump, often can run into have bubble in pump barrel, and raise when a large amount of bubbles can not get will making when effectively discharging the pump barrel internal air pressure, cause and can't normally recover the oil.

Summary of the invention

The purpose of this utility model is to provide a kind of efficient lengthening and returns oil pipe exhaust oil well pump, has solved when petroleum production in pump barrel that gas can not get effectively discharging and the normal problem of recover petroleum.

The technological scheme that the utility model adopts is, oil pipe exhaust oil well pump is returned in a kind of efficient lengthening, 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, anti-that ball seat and liquid inlet pipe from top to bottom, is socketed with in liquid inlet pipe and returns oil pipe, ectosome supervisor top has relief opening, ectosome supervisor's relief opening below has liquid entering hole, and the bottom of liquid inlet pipe has inlet opening, returns that liquid inlet pipe is stretched out in the oil pipe lower end and extrusion is 10-20m.

The beneficial effects of the utility model are form the space between ectosome supervisor and oil pump main body, and then a large amount of gas to be discharged from, the oil pipe that returns that lengthens inserts in the pump sandpipe of bottom, so utilize balanced action, suppress gas and scurry in pump barrel, make oil to be exploited smoothly.

Description of drawings

Fig. 1 is the structural representation that oil pipe exhaust oil well pump is returned in a kind of efficient lengthening 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.

Embodiment

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

The utility model provides a kind of efficient lengthening to return oil pipe exhaust oil well pump, 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, anti-that ball seat 5 and liquid inlet pipe 6 from top to bottom, be socketed with in liquid inlet pipe 6 and return oil pipe 7, ectosome supervisor 1 top has relief opening 8, ectosome supervisor 1 relief opening 8 belows have liquid entering hole 9, the bottom of liquid inlet pipe 6 has inlet opening 10, returns that liquid inlet pipe 6 is stretched out in oil pipe 7 lower ends and extrusion is 10-20m.

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 gases are discharged from by relief opening 8, to return simultaneously oil pipe 7 lengthens, the oil pipe 7 that returns that lengthens inserts in the pump sandpipe of bottom, so utilize balanced action, suppressing gas scurries in pump barrel, alleviated like this air pressure in pump barrel, improved the efficient of oil well pump, the oil of down-hole can be exploited out smoothly.

Claims

1. efficient a lengthening returned oil pipe exhaust oil well pump, it is characterized in that, 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) from top to bottom, oil drainer (4), anti-that ball seat (5) and liquid inlet pipe (6), be socketed with in liquid inlet pipe (6) and return oil pipe (7), ectosome supervisor (1) top has relief opening (8), have liquid entering hole (9) below ectosome supervisor's (1) relief opening (8), the bottom of liquid inlet pipe (6) has inlet opening (10), describedly return that liquid inlet pipe (6) is stretched out in oil pipe (7) lower end and extrusion is 10-20m.
