The Type of HQ Wireline Overshots
PEERCHEER offers compact BQ Ezy lock overshots for use with hq wireline overshots.
Working Principle
When the salvager enters the center tube of the drill bit, the slider moves up, so that the salvager head can be inserted into the center tube. When the slider is up, the slider moves down and tightens, and the friction bit is used to lift the drill bit. The connecting rope on the slide will tighten tightly, just pull out the center tube.
Before salvaging, you must first determine the position of the drill bit at the bottom of the hole. A thin plate can be bolted to the bottom of the drill rod. The drill rod can be dropped to the bottom of the hole and pressed onto the drill bit. The indentation left to determine the relative position of the hole bottom drill bit and the center of the drill turret, and then move the rig or turntable so that the center of the turntable is facing the center tube of the wound head, then it can ensure that the fishing device can be accurately inserted into the center tube.
Key points of operation:
(1) Measure the length of the salvage tubing, verify the depth of the fish roof well, and the salvage entry
(2) Select the fishing tool and go down the fishing pole to explore the fish top
(3) Salvage in combination with the salvage tools used
(4) Trial mention, if the reading of the dynamometer increases obviously, indicating that it has been held, then lift the pipe string steadily and remove the falling objects.
(5) If a card is encountered after fishing, the card will be unlocked or reversed, the salvage pipe will be pulled out, and the next step will be studied.
