Abstract
The invention relates to a sand wash valve applied in the petroleum industry. The sand wash valve comprises a valve body, a cavity connected with an oil pipe is formed in the valve body, a valve seat is arranged on the upper part of the cavity, a valve ball matched with the valve seat is arranged on the valve seat, and a pressure spring is arranged on the upper part of the valve ball. During the operation under pressure, the sand wash valve has the effects of snubbing and blowout control, and sand washing can be realized through a well head suppressing method, so that the sand wash valve is a novel tool used in the operation under pressure.
Description
Technical field
The present invention relates to a kind of scouring sluice that is applied in the petroleum industry.
Background technology
In the deep layer oil producing operation, in oil pipe is gone into the well process,, during underground work that particularly sand content is big, especially need a kind of scouring sluice carry out sand washing, to guarantee carrying out smoothly of oil producing operation because strata pressure is big, cause crude oil to be prone to spray.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of down-hole, oil field that is applicable to carry out the scouring sluice of sand washing operation.
Technical scheme of the present invention is: the present invention includes valve body, be provided with the cavity that is connected with oil pipe in the valve body, valve seat is established on cavity top, and valve seat is provided with the valve ball that cooperates with valve seat, and valve ball top is provided with compression spring.
The compression spring place is provided with the spring pressure adjusting nut.
Advantage of the present invention is: the present invention plays not kill-job in Operating Pressure, and the effect of blowout prevention can realize sand washing through the method that well head is suppressed again, is a kind of novel Operating Pressure instrument.
Description of drawings
Fig. 1 is a structural representation of the present invention
1 is that cavity, 2 is that valve seat back-up ring, 3 is that valve seat, 4 is that valve ball, 5 is that spring base, 6 is that compression spring, 7 is the spring pressure adjusting nut among the figure.
The specific embodiment
The valve body of scouring sluice of the present invention is provided with the cavity 1 that is connected with oil pipe; Cavity 1 top is provided with valve seat 3; Be provided with the valve seat back-up ring 2 that supports valve seat 3 between cavity 1 and the valve seat 3, valve seat 3 is provided with the valve ball 4 that cooperates with valve seat 3, and the end of valve body is provided with the compression spring 6 that is connected with valve ball 4; Compression spring 6 acts on valve ball 4 through spring base 5, and the end of valve body is established the spring pressure adjusting nut of regulating compression spring 6.
Operating principle of the present invention is: the present invention is connected the cavity 1 of Operating Pressure scouring sluice the top of sand clean out pipe; Go into the well with oil pipe; The Operating Pressure scouring sluice is under the operation of stratum oil pressure and compression spring 6 pressure; Valve ball 4 is pressed on the valve seat 3, and hydraulic oil stream and gases at high pressure in the pit shaft are closed in outside the oil pipe, can realize down the band pressure effect of oil pipe.When oil pipe descends the design well depth, at well head oil pipe is linked to each other with pump truck, when pump pressure reaches 8～12MPa, overcome compression spring 6 elastic force and strata pressure, valve ball 4 is opened, and can realize the sand washing operation.
Claims (2)
1. scouring sluice is characterized in that, comprises valve body, is provided with the cavity that is connected with oil pipe in the valve body, and valve seat is established on cavity top, and valve seat is provided with the valve ball that cooperates with valve seat, and valve ball top is provided with compression spring.
2. scouring sluice according to claim 1 is characterized in that the compression spring place is provided with the spring pressure adjusting nut.
