Embodiment 1

[0030] Embodiment 1, with reference to attached Figure 1-Figure 5 , an oil well compound anti-sand plugging ball seat provided by the present invention, comprising oil pipe 1, ball seat 2, driving box 3, movable block 4, pressing device 5 and steel ball 6;

[0031] Further, the ball seat 2 is arranged inside the oil pipe 1. 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 a bump 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 a bump 21, and the upper end of the bump 21 is welded to connect the spring 211, and then the top of the connection 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 to play a fixed role to prevent the ball s...

Embodiment 2

[0038] Embodiment 2, with reference to attached Figure 6 , an oil well compound anti-sand plugging ball seat provided by the present invention, comprising a pressing device 5;

[0039] Further, the pressing device 5 is welded on the top of the movable block 4, the pressing device 5 includes an arc-shaped pressing post 52, and the arc-shaped pressing post 52 is welded on the top of the movable block 4, because the arc-shaped pressing post 52 is welded on the top of the movable block 4 , the arc-shaped pressing column 52 is arranged at the bottom 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: those skilled in the art drop the steel ball 6 from the top of the oil pipe and drop it inside the ball groove 22, so that the steel ball 6 touches the pressing device 5, so that the ...

Abstract

The invention discloses an oil well combined type sand-blocking-preventing ball seat and a method. The oil well combined type sand-blocking-preventing ball seat comprises an oil pipe, the interior ofthe oil pipe is connected with a ball seat body, driving boxes are clamped to the two ends of the interior of the ball seat body, a movable block is clamped to the lower end of the interior of the ball seat body, a pressing device is welded to the upper end of the movable block, and a steel ball is arranged at the upper end of the ball seat body. A fixed block is welded to the left end of the inner wall of each driving box, the surface of the right end of each fixed block is sleeved with a tough spring, the right end of each tough spring is sleeved with the outer wall of the left side of a movable baffle, the left end of each movable baffle is inserted into the corresponding driving box, and a movable block is sleeved with the right end of each driving box. Each pressing device comprises ahemispheric pressing column, each hemispheric pressing column is welded to the top end of the corresponding movable block, and convex blocks are arranged at the two ends of the outer wall of the ballseat body. The oil well combined type sand-blocking-preventing ball seat has the beneficial effects that the ball seat body is prevented from being blocked by sandy soil in transported oil, it is guaranteed that the oil can be continuously transported, and therefore the exploitation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of petroleum industry, in particular to an oil well composite anti-sand plugging ball seat and a method thereof. Background technique [0002] The oil well is the hole drilled according to the well layout system of the oil field development plan for the exploitation of oil, and the oil rises from the bottom of the well to the well head; [0003] An oil well is a hole drilled by drilling methods. Generally, after an oil well is drilled into the oil layer, it is lowered into the oil layer casing, and 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. According to the requirements of oilfield development, use a perforating gun to open the oil layer to form a channel, lower it into the oil pipe, and use a suitable induction method to raise the oil from the bottom of the oil well to the head of the well; [0004] The oil...
