Application It is suitable for all conventional wells, inclined wells and large displacement wells at all temperatures not higher than 204℃.

Features

The superior machine structure is to further improve the machine maintainability. The unique sealing structure is designed to improve the temperature resistance and improve the sealing reliability. The core mechanism adopts the seal oil bath design to reduce the wear and tear of the moving parts and improve the life of the whole machine.

The overflow area of the release channel is increased to reduce the running resistance and greatly improve the shock effect.

The operating force of hydraulic releasing mechanism can be controlled on the ground by driller, and can be flexibly adjusted according to the downhole situation.

The optional mechanical locking module is added to meet the needs of some special users.
