Abstract
The utility model discloses a high liquid level exhaust pump which comprises an outer main tube. A pump body is nested in the outer main tube and 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 lower portion of the liquid inlet tube is provided with a first liquid inlet. The upper portion of the outer main tube is provided with a second liquid inlet. An exhaust tube is disposed at the top of the space between the outer main tube and the pump body. The problem that failure of normal oil extraction is caused by excessively high liquid level, a liquid-sealed exhaust hole of the exhaust pump and failure of effective discharge of the gas in a pump barrel during oil extraction is solved.
Description
Technical field
The utility model belongs to the oil exploration equipment technical field, relates to a kind of high liquid level (HLL) operating mode exhaust pump.
Background technique
When carrying out petroleum production with oil well pump; often can run into and 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; if the submergence of pump is very large; liquid level in pit shaft is very high; can cause the exhaust port of existing exhaust pump by fluid-tight, and be difficult for exhaust, and then cause and normally to recover the oil.
Summary of the invention
The purpose of this utility model is to provide a kind of high liquid level (HLL) operating mode exhaust pump, has solved when petroleum production because liquid level is too high, and the exhaust port of exhaust pump is by fluid-tight, and in pump barrel, gas can not get effectively discharging and the normal problem of recover petroleum.
The technological scheme that the utility model adopts is, a kind of high liquid level (HLL) operating mode exhaust pump, 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, and the bottom of liquid inlet pipe has inlet opening, ectosome supervisor top has inlet opening, and the top end between ectosome supervisor and oil pump main body is provided with outlet pipe.
Characteristics of the present utility model also are,
Return wherein that liquid inlet pipe is stretched out in the oil pipe lower end and extrusion is 10-20m.
Wherein be provided with some oil baffles between ectosome supervisor and oil pump main body.
The beneficial effects of the utility model are form the space between ectosome supervisor and oil pump main body, and then gas to be discharged from a large number, makes oil to be exploited smoothly.
Description of drawings
Fig. 1 is the structural representation of a kind of high liquid level (HLL) operating mode of the utility model exhaust pump.
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. inlet opening, 9. outlet pipe, 10. inlet opening, 11. oil baffles.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model provides a kind of high liquid level (HLL) operating mode exhaust 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, is socketed with in liquid inlet pipe 6 and returns oil pipe 7, and the bottom of liquid inlet pipe 6 has inlet opening 10, ectosome supervisor 1 top has inlet opening 8, and the top end between ectosome supervisor 1 and oil pump main body 2 is provided with outlet pipe 9.Return wherein that liquid inlet pipe 6 is stretched out in oil pipe 7 lower ends and extrusion is 10-20m.Be provided with some oil baffles 11 between ectosome supervisor 1 and oil pump main body 2.
Inlet opening 8 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 inlet opening 8 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 outlet pipe 9.If it is very high to run into the interior liquid level of pit shaft, after ectosome supervisor 1 outer fluid was entered by inlet opening 8, gas can rise, and was discharged by outlet pipe 9, did not cause gas to discharge and can not flooded by fluid.
Simultaneously, owing to being provided with some oil baffles 11 between ectosome supervisor 1 and oil pump main body 2, so when liquid during from inlet opening 8 feed liquor, the sedimentation downwards of liquid left and right, and large quantity of fluid is splashed by oil baffle 11 and is scattered, and then gases are discharged from a large number, have alleviated like this air pressure in pump barrel, and the oil of down-hole can be exploited out smoothly.And will return oil pipe 7 and add to grow to and stretch out liquid inlet pipe 6 and extrusion is 10-20m, the oil pipe 7 that returns of lengthening inserts in the pump sandpipe of bottom, so utilize balanced action, suppresses gas and scurries in pump barrel, more is beneficial to the discharge of gas.
