Double-acting mechanical-hydraulic drilling jar integrates upward jarring with downward jarring hydraulic drilling jar with mechanical interlocking. It can suit for all kinds of drilling operations, and landing into the well with drilling tools assembly when used. When the drilling tools are stuck, it can make drilling jar generate upward or downward jarring force through lifting and landing the drill strings, so it can release resistance and the stick by many time jarring, and recover normal drilling operation promptly. If adjust the release force, it can be adjusted any time on the spot.
We also produce H2S resistance Jars, which adopt high quality import sulfur-resistance material.
