Hydraulic Pressure Damping LoadNera Hydraulic Pressure Damping Load is well-structured and practical, achieced the National Utility Model. It is a downhole tool for petroleum and gas drilling. When it works, drill liquid circulating pressure works on drill bit, it has the function of absorbing shock, bit feeding automatically and deviation preventing, as well as the function of speeding up drilling, reducing labour intensity and protecting drill bit and drill tool. It can recruit the pressure lost in slide drilling and overcome the difficulty in adding pressure so that it is quite fit for deviation control and drilling fast in extended reach well,horizontal well, directional well and post hole, as well as fit for adding pressure and absorbing shocking in common straight well drilling.
