Detailed introduction

Type DQJ Top Drive Shock Absorber is a new type of wellhead top drive shock sub, which is connected between top drive and DP. It is mainly used to protect top drive when drilling tool trips in shallow Wells. It absorbs the bouncing and vibration of the drilling tool through the compression of two damping spring elements, disc spring and silicone oil. It has shock absorption function in both tension and compression, which can effectively reduce the vibration impact of bouncing on the top drive, and then has a good protective effect on top drive.
