Double Acting Drilling Accelerator

Double Acting Drilling Accelerator

The double acting drilling intensifier is a downhole drilling tool to enhance jarring function for the full hydraulic drilling jar, so it must be used with the full hydraulic drilling jar together. It has hydraulic spring as the energy storage element and the structure design itself has no jarring function. The double acting drilling jar can intensify the drill collar and drilling jar which are connected under it to get more stronger jarring force, meanwhile it can reduce destroy for the drilling tools on the upper side of the intensifier during the upward or downward jarring operation.
