Lubricated fishing bumper sub is one of the jars which produce jarring force by means of the energy caused by heavy weight objects when moving down, its inner chamber is full of hydraulic oil so as to ensure a longer service life. The tool is suitable for deep hole and middle deep hole operation. With some advantages: Can produce strong one way down jarring force, maximum jarring force, continuous down jarring force. Medium jarring force; continuous up jar, low-grade jarring force; can release fishing tool; can act as constant pressure drill tool, simply structure, easy operation, all these make it widely used jarring tool.
A bumper sub is a downhole tool commonly used in oil and gas drilling operations, particularly during fishing, coring, and workover activities. Its primary function is to provide axial movement within the drill string, allowing operators to deliver controlled impacts or "jars" to downhole equipment. This capability is essential for freeing stuck tools, retrieving lost equipment, and facilitating various downhole interventions.
