Abstract
The utility model relates to a sand washing oil well pump, which comprises an oil well pump, a by-pass valve connected with an upper end of the oil well pump, which is characterized in that: the by-pass valve comprises a valve body, a sliding sleeve in the valve body, a sealing ring outside a sliding sleeve, a reset spring on the lower end of the sliding sleeve, a locating ring connected with the upper part of the valve body; a water hole is arranged on the middle upper part of the valve body; also comprises the sand washing pipe outside the by-pass valve and the oil well pump, a sand washing head connected with the lower end of the sand washing pipe. In the utility model, since the by-pass valve is arranged on the upper end of the oil well pump, the sand washing pipe is arranged outside the by-pass valve and the oil well pump, so the sand washing with pump can be carried out at any moment, to take out the oil well pump and to lay the sand washing string for the sand washing is unnecessary, so as to reduce procedures, relieve labor intensity, and reduce oil exploitation cost.
Description
Technical field
The utility model relates to oil exploration equipment, is specifically related to a kind of sand washing oil well pump.
Background technique
In the petroleum production process, containing sand in the crude oil is universal phenomenon.Sand grains is clipped in the crude oil can quicken the wearing and tearing of oil well pump, the oil pumping pump efficiency is reduced gradually, shorten working life, and when the sand in the oil well deposited to certain thickness, oil well pump just can't be worked, therefore, need change oil well pump continually, also will descend the sand washing tubing string simultaneously in addition to oil well sand washing, after sand washing finishes, trip out the sand washing tubing string, and then pump from oil well pump down.So not only workload is big, and efficient is low, and cost is very high.Occurred some sand flushing devices afterwards again, and as ZL96228975 disclosed " a kind of scouring sluice ", got final product the sand washing operation though can play pump, its structure is comparatively complicated, need be improved.
Summary of the invention
The purpose of this utility model provides a kind of sand washing oil well pump, and it is simple in structure, uses reliably, can be with pump sand washing at any time, and is easy and simple to handle, sand washing efficient height.
A kind of sand washing oil well pump described in the utility model, comprise oil well pump, be connected the bypass valve of oil well pump upper end, it is characterized in that: bypass valve by valve body, be located at sliding sleeve in the valve body, be located at the sliding sleeve outside seal ring, be located at the Returnning spring of sliding sleeve lower end, the positioning ring that is connected valve body top is formed; Middle and upper part at valve body is provided with the water port; Also comprise the sand clean out pipe that is located at bypass valve and oil well pump outside, the sand washing head that is connected the sand clean out pipe lower end.Its sand clean out pipe is formed by connecting by the above steel pipe of a joint.
The utility model is owing to be provided with bypass valve in the upper end of oil well pump, outside at bypass valve and oil well pump is provided with sand clean out pipe, thereby can be with the pump sand washing at any time, do not carry out sand washing and do not need to trip out other following sand washing tubing string of oil well pump, reduced operation, alleviate labor intensity, reduced cost of oil production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1, seal ring 4 is enclosed within the outside of sliding sleeve 3, reinstall the middle and upper part be provided with water port 7 by in the valve body 2, Returnning spring 5 is installed in the lower end of sliding sleeve, positioning ring 6 is connected the top of valve body, promptly constitutes bypass valve; Bypass valve is connected the upper end of oil well pump 1, and the sand clean out pipe 8 that is formed by connecting by the above steel pipe of a joint is installed in the outside of bypass valve and oil well pump, and sand washing head 9 is connected getting final product of sand clean out pipe 8.
When needs stop to pump sand washing, sucker rod is transferred to the shaft bottom, the box cupling that connects pump rod and sucker rod is passed sliding sleeve 3 downwards, compression reseting spring 5, open the water port 7 of valve body 2 middle and upper parts of bypass valve, start the ground water pump and carry out sand washing, clear water is injected in the oil pipe, the high pressure clear water through the water port 7 and the annulus access of sand clean out pipe 8 and oil well pump penetrate and impact sand setting, the high pressure clear water carries loose sand and routs up ground from the annulus access of oil pipe and oil well casing.
After sand washing finishes, will carry on the sucker rod, be connected with pumping unit, sliding sleeve 3 moves up under the effect of Returnning spring 5, closes the water port 7 of valve body 2 middle and upper parts of bypass valve, can continue oil pumping.
Claims (2)
1, a kind of sand washing oil well pump, comprise oil well pump (1), be connected the bypass valve of oil well pump upper end, it is characterized in that: bypass valve by valve body (2), be located at sliding sleeve (3) in the valve body, be located at the sliding sleeve outside seal ring (4), be located at the Returnning spring (5) of sliding sleeve lower end, the positioning ring (6) that is connected valve body top is formed; Be provided with water port (7) in the middle and upper part of valve body (2); Also comprise the sand clean out pipe (8) that is located at bypass valve and oil well pump outside, the sand washing head (9) that is connected the sand clean out pipe lower end.
2, a kind of sand washing oil well pump according to claim 1 is characterized in that: sand clean out pipe (8) is formed by connecting by the above steel pipe of a joint.
