The to-be-solved technical problem of the utility model lies in providing a bridge plug setting releasing adapter that can realize that one trip tubular column accomplishes big latus rectum bridge plug setting releasing and tests to seal.
The utility model provides a technical scheme that its technical problem adopted is: the large-drift-diameter bridge plug setting releasing adapter capable of automatically releasing the plugging balls underground is constructed and comprises a push cylinder, a connecting cylinder, the plugging balls and a pull rod, wherein the connecting cylinder is located inside the push cylinder, the left end of the push cylinder is connected with a setting tool, and the right end of the push cylinder is tightly attached to a retaining ring of the bridge plug; the connecting cylinder left end still includes double-end hinge rod with sit and seal instrument dabber and be connected, the left end of pull rod pass through double-end hinge rod with the connecting cylinder is connected, the right-hand member of pull rod passes through shear pin and is connected with the bridging plug, the pull rod is the cylinder, and it includes that many cross sections are fan-shaped cylinder.
In the above scheme, the pull rod penetrates through a central pipe of the bridge plug.
In the above scheme, the blocking ball is placed in the connecting cylinder.
In the scheme, the right end of the connecting cylinder is connected with the double-end hinge rod through a hinge.
In the scheme, the left end of the pull rod is connected with the double-end hinge rod through a hinge.
Implement the utility model discloses a bridge plug setting release adapter has following beneficial effect:
1. bridge plug setting release adapter and bridge plug setting instrument, big latus rectum bridge plug are connected and carry the design position along with other instruments through the cable together, then through the cable to setting instrument circular telegram, explode the gunpowder in the setting instrument and realize bridge plug setting release, lift cable to perforation position blocking ball automatic roll out from bridge plug adapter inside simultaneously, reach the ball seat under the effect of pit shaft liquid flow thrust. And injecting liquid into the shaft, pressurizing, and checking the seal of the large drift diameter.
2. The utility model discloses use with the cooperation of big latus rectum bridging plug, accomplish bridging plug and sit to seal and can test sealing of giving up, reduce the process of hydraulic pump ball simultaneously, reduce the use amount of water, promote the efficiency of construction, reduce the operating cost.
