Specific embodiment
Below in conjunction with attached drawing, the present invention is further described:
The sand control installation referring to Fig. 1, a kind of horizontal well in segments is handled up, including transition joint 3, fixing seat 2, release spring 5,
Stabilizing spring 7, spring base 9, ball seat 10, pressure cap 12 and steel ball 11；Transition joint 3 is hollow tubular, and ball seat 10 is co-axially located at
On the inside of one end of transition joint 3, the transition joint 3 of 10 side of ball seat is provided with pressure cap 12, and the setting of steel ball 11 is in ball seat 10 and pressure
In space between cap 12, stabilizing spring 7 is provided between steel ball 11 and pressure cap 12, steel ball can be pressed in ball by stabilizing spring 7
On seat 10；Ball seat 10 is provided with spring base 9 far from the side of steel ball 11, is provided with and releases between one end and ball seat 10 of spring base 9
Spring 5 is put, the other end of spring base 9 is connected and fixed seat 2.Ball seat 10 is packed into 3 lower end of transition joint；By steel ball 11 and stablize bullet
Spring 7 is sequentially loaded into ball seat 10；Pressure cap 12 is threadedly coupled with transition joint 3；Release spring 5 is caught in spring base 9, closely
10 top of ball seat；
The middle part of spring base 9 is provided with annular protrusion, and release spring 5 is arranged between annular protrusion and ball seat 10, and locates
In compressive state；Sealing rubber ring 6 is provided between 3 inner wall of ball seat 10 and transition joint.
Fixing seat is the tubular of single-open, and the end of spring base 9 is inserted in fixing seat 2, and spring base 9 and fixing seat 2
Pass through 4 connection of shearing nail.Spring base 9 is fixedly connected with fixing seat 2 by shear pin 4；
