Introduction：

The fully mechanical drilling jar is a downhole jarring tool for stuck pipe release while drilling. The triggering mechanism of this tool is entirely mechanical, enabling both upward and downward jarring operations for stuck pipe release. It is simple to operate and delivers stable jarring force, featuring a mechanical locking function that effectively prevents unnecessary jarring during drilling operations. This tool can quickly and effectively resolve stuck pipe incidents, such as drill string sticking or obstruction, encountered during drilling operations.

Features and Benefits：

★ The triggering mechanism is fully mechanical, making operation simple and reliable.

★ It features a mechanical locking function to effectively prevent accidental jarring.

★ It enables rapid bidirectional jarring for efficient resolution of downhole sticking.
