Its main advantages are simple structure, reliable working performance, convenient operation and maintenance, well absorbing shock and vibration loads generated by the drill string during drilling operations. The benefits of using the shock absorber are that it helps to enhance the service life of drill bit and drill tools, improves drilling speed and efficiency, and overcomes the serious bit jump. It is very reliable to ensure normal drilling operation and protect ground equipment and drilling tools.
