Embodiment 1

[0030] Example 1, with reference to the attached Figure 1-Figure 5 , The present invention provides an oil well compound sand control ball seat, comprising an oil pipe 1, a ball seat 2, a drive box 3, a movable block 4, a pressing device 5 and a steel ball 6;

[0031] Further, the ball seat 2 is arranged inside the oil pipe 1, and the ball seat 2 includes a bump 21, a connecting spring 211 and a ball groove 22. Specifically, the two ends of the outer wall of the ball seat 2 are provided with bumps 21, and the upper end of the bump 21 is welded to connect the spring 211. The top of the ball seat 2 is provided with a ball groove 22, and the two ends of the outer wall of the ball seat 2 are provided with bumps 21. The upper end of the bump 21 is welded to the connecting spring 211, and then the top of the connecting spring 211 is welded to the inside of the oil pipe 1 to make the ball. The seat 2 is connected to the inside of the oil pipe 1 and plays a fixed role to prevent the ...

Embodiment 2

[0038] Example 2, with reference to the attached Image 6 , the present invention provides an oil well compound sand control plugging ball seat, comprising a pressing device 5;

[0039] Further, the pressing device 5 is welded on the top of the movable block 4 , and the pressing device 5 includes an arc-shaped pressing column 52 , and the arc-shaped pressing column 52 is welded on the top of the movable block 4 . , The arc-shaped pressing column 52 is arranged at the bottom end of the ball groove 22, so that the steel ball 6 can press the arc-shaped pressing column 52 to play a pressing role, and achieve the effect of opening the movable baffle 33 to transport oil;

[0040] The use process of the present invention is as follows: a person skilled in the art throws the steel ball 6 from the top of the oil pipe and falls inside the ball groove 22, so that the steel ball 6 touches the pressing device 5, so that the pressing device 5 drives the movable block 4 to move down , since...

Abstract

The invention discloses an oil well composite anti-sand plugging ball seat and a method thereof. The technical proposal is as follows: an oil pipe is connected inside the oil pipe to a ball seat; The movable block is clamped, the upper end of the movable block is welded with a pressing device, the upper end of the ball seat is provided with a steel ball, the left end of the inner wall of the drive box is welded with a fixed block, the right end surface of the fixed block is sleeved with a resilient spring, and the right end of the resilient spring is The left outer wall of the movable baffle is socketed, the left end of the movable baffle is plugged into the inside of the drive box, the right end of the drive box is socketed with the movable block, the pressing device includes a hemispherical pressing column, and the hemispherical The shaped pressing column is welded on the top of the movable block, and the two ends of the outer wall of the ball seat are provided with bumps. The beneficial effect of the present invention is: to prevent the ball seat from being blocked by sand and soil inside the transported oil, to ensure that the oil can be continuously transported, thereby increasing the production capacity. efficiency effect.

Description

technical field [0001] The invention relates to the technical field of the petroleum industry, in particular to an oil well compound sand-control plugging ball seat and a method. Background technique [0002] The oil well is the hole drilled by the well layout system according to the oilfield development plan for oil extraction, and the oil rises from the bottom of the well to the wellhead; [0003] Oil wells are holes drilled by drilling methods. Generally, after drilling the oil layer, the oil well is run into the oil layer casing, and the oil well cement is injected into the annular space between the casing and the well wall to maintain the well wall and seal oil, gas and water. Then, according to the requirements of oilfield development, the oil layer is shot with a perforating gun to form a channel, and the oil pipe is lowered into the oil pipe, and the oil is raised from the bottom of the oil well to the wellhead by the appropriate inducing method; [0004] Oil pipeli...
