Abstract
The invention discloses a kind of exhaust pump that can solve high liquid level (HLL) exhaust problem, comprise ectosome supervisor, oil pump main body is socketed with in ectosome supervisor, oil pump main body is disposed with pump core, oil drainer, anti-that ball seat and liquid inlet pipe from top to bottom, be socketed with in liquid inlet pipe and return oil pipe, the bottom of liquid inlet pipe has inlet opening, and ectosome supervisor top has inlet opening, and the top end between ectosome supervisor and oil pump main body is provided with outlet pipe.Solve when petroleum production because liquid level is too high, the exhaust port of exhaust pump is by fluid-tight, and in pump barrel, gas can not get effectively discharging and cannot the problem of normal recover petroleum.
Description
Technical field
The invention belongs to oil exploration equipment technical field, relate to a kind of exhaust pump that can solve high liquid level (HLL) exhaust problem.
Background technique
When carrying out petroleum production with oil well pump; often can run into and there is bubble in pump barrel; and pump barrel internal air pressure will be made to raise when a large amount of bubble can not get effectively discharging; if the submergence of pump is very large; liquid level in pit shaft is very high; the exhaust port of existing exhaust pump can be caused by fluid-tight, and be not easily vented, and then cause normally recovering the oil.
Summary of the invention
The object of this invention is to provide a kind of exhaust pump that can solve high liquid level (HLL) exhaust problem, solve when petroleum production because liquid level is too high, the exhaust port of exhaust pump is by fluid-tight, and in pump barrel, gas can not get effectively discharging and cannot the problem of normal recover petroleum.
The technical solution adopted in the present invention is, a kind of exhaust pump that can solve high liquid level (HLL) exhaust problem, comprise ectosome supervisor, oil pump main body is socketed with in ectosome supervisor, some oil baffles are provided with between ectosome supervisor and oil pump main body, oil pump main body is disposed with pump core from top to bottom, oil drainer, anti-that ball seat and liquid inlet pipe, be socketed with in liquid inlet pipe and return oil pipe, return oil pipe lower end and stretch out liquid inlet pipe and extrusion is 10-20m, the bottom of liquid inlet pipe has inlet opening b, ectosome supervisor top has inlet opening a, top end between ectosome supervisor and oil pump main body is provided with outlet pipe, inlet opening a is higher than the bottom of pump core.
The invention has the beneficial effects as follows, between ectosome supervisor and oil pump main body, form space, and then a large amount of gas is discharged, and oil can be exploited smoothly.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation that can solve the exhaust pump of high liquid level (HLL) exhaust problem of the present invention.
In figure, 1. ectosome supervisor, 2. oil pump main body, 3. pump core, 4. oil drainer, 5. anti-that ball seat, 6. liquid inlet pipe, 7. return oil pipe, 8. inlet opening a, 9. outlet pipe, 10. inlet opening b, 11. oil baffles.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The invention provides a kind of exhaust pump that can solve high liquid level (HLL) exhaust problem, as shown in Figure 1, comprise ectosome supervisor 1, oil pump main body 2 is socketed with 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, and be socketed with in liquid inlet pipe 6 and return oil pipe 7, the bottom of liquid inlet pipe 6 has inlet opening b10, ectosome is responsible for 1 top and is had inlet opening a8, and the top end between ectosome supervisor 1 and oil pump main body 2 is provided with outlet pipe 9.Wherein return oil pipe 7 lower end and stretch out liquid inlet pipe 6 and extrusion is 10-20m.Some oil baffles 11 are provided with between ectosome supervisor 1 and oil pump main body 2.
Inlet opening a8 in oil well pump of the present invention, higher than the bottom of pump core 3, when oil well pump works, forms space between ectosome supervisor 1 and oil pump main body 2, so during inlet opening a8 feed liquor, the downward sedimentation of liquid, gas is responsible for 1 inwall along ectosome and is upwards spread, and then a large amount of gas is discharged by outlet pipe 9.If it is very high to run into liquid level in pit shaft, after the fluid outside ectosome supervisor 1 is entered by inlet opening a8, gas can rise, and is discharged by outlet pipe 9, and can not be flooded by fluid and cause gas to discharge.
Simultaneously, owing to being provided with some oil baffles 11 between ectosome supervisor 1 and oil pump main body 2, so when liquid is from inlet opening a8 feed liquor, downward sedimentation about liquid, and large quantity of fluid is splashed by oil baffle 11 and is scattered, and then a large amount of gas is discharged, and alleviates the air pressure in pump barrel like this, makes the oil of down-hole be exploited out smoothly.And will return oil pipe 7 to 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 to be scurried in pump barrel, is more beneficial to the discharge of gas.
