Releasable Spear
Alloy Steel&Nickel Alloy
China Baoji
Wireline Operation And Slickline Operation
Standard
The Releasable Spear is used to fish the wells with inner holes. It is simple and easy to use.
Releasable Spear is composed of an upper joint, a mandrel, an auxiliary spring seat, an outer cylinder, a cone and slips. The slip is sleeved on the cone, and the slip is moved up and down along the cone surface of the cone through the compression and expansion of the spring, and the diameter of the slip is changed, thereby changing the fishing range and fishing fish with different inner hole diameter ranges. After the salvage meets obstacles, you can slam the pin downwards, throw off the fish, and raise the salvage spear.

Note. More customized parts are available upon request.
1. The method of using the self-released slip fishing spear. When fishing down the well, the slip moves on the cone surface of the cone to change the diameter of the slip, thereby fishing the fish with different bore diameters.
2. When pulling out, by cutting the shear pin, under the force of the main spring, the outer cylinder drives the slips to move upward, and the fishing spear is raised.
3. Releasable Spear needs to reinstall the pin every time the operation is completed. When installing the pin, use the equipped pin installation tool.
1. Tighten the slips when replacing them.
2. When replacing the pin, the slip and hexagon bolt must be removed to facilitate the use of the pin installation tool.
