| High Light | hydraulic-mechanical drilling jar ，downhole drilling jar with high jarring force ，YJZ drilling jar with tensile load | ||
The YJZ type hydraulic-mechanical drilling jar integrates hydraulic and mechanical principles and is designed for various drilling operations when combined with drilling tools. When downhole tools become stuck, this equipment generates upward or downward jarring forces through lifting and landing drilling strings. Multiple jarring actions can release blocks and stuck tools, enabling prompt resumption of normal drilling operations.
This technology helps prevent resistance and sticking that could lead to further accidents and significant economic losses. If initial releasing force proves insufficient, the system allows for dynamic adjustment on-site at any time.
