Background technology
When carrying out down-hole oil production in the oil field at present, usually before oil well pump, use sand control, the antiresiduum device that has valve, block to guarantee the foreign material such as sand that oil well pump is not mixed in the oil, but existing sand control, antiresiduum device are used for carrying out the position of sand setting and mostly are space between central tube and the outer tube, but this space is very limited, when being used to contain sand well recovery how, must carrying out the sand removal repairing with carrying on this sand control, the antiresiduum device, and influence normally carrying out of oil extraction operation in common 2~3 days.
Summary of the invention
The utility model provides a kind of sand setting bleeder, to solve the too small problem in space that present sand control, antiresiduum device are used for settled sand, slag.The technical scheme that the utility model is taked is: top connection 1 is fixedlyed connected with outer tube 3 screw threads, the other end of this outer tube 3 is fixedlyed connected with lower contact 2 screw threads, lower contact 2 is fixedlyed connected with following valve cover 4 screw threads, place valve seat 41 and following valve ball 42 down in this time valve cover, oil pumping hole 5 is arranged in this lower contact 2, in this lower contact 2 sand setting through hole 6 is arranged, this sand setting through hole 6 does not communicate fixedly connected sand tube 7 of these lower contact 2 bottom thread or sand plug 7 ' with oil pumping hole 5.
In another embodiment of the utility model: the fixedly connected valve cover 8 of going up of following valve cover 4 screw threads, inner placement of valve cover gone up valve seat 81 and last valve ball 82 on this, and oil outlet 83 is arranged at valve cover top on this.
In another embodiment of the utility model: in top connection 1, connect draining sliding sleeve 9, have draining hole 11 with the corresponding site that this draining sliding sleeve is connected in top connection by shear pin.
In another embodiment of the utility model: oil pumping hole 5 external fixation in lower contact 2 connect sand control screens 10.
During use, oil enters lower contact from the oil pumping hole in oil pumping process, through following valve, go up valve, enters from top connection at last in the oil well pump, is deposited to sand in the oil or the slag sand setting through hole from lower contact in the sand tube that the lower contact bottom connects.
The utility model advantage is: novel structure, the sand or the slag that utilize the sand tube to store to settle down have the big characteristics of reserves, when containing husky high oil well and use, can guarantee normally to use more than 2~March, have reduced the maintenance cost of oil well.Improved oil recovery efficiency greatly.
