downhole tool for oil drilling

Hydraulic Pressure Damping Load

 

The product is well-structured and practical.

It is a downhole tool for petroleum and gas drilling, in which drill liquid circulating pressure works on drill bit, it has the function of damping, bit feeding automatically and deviation preventing, as well as the function of speeding up drilling, reducing labor intensity and drill bit and drill tool protection.

It can recruit the pressure lost in slide drilling and overcome the difficult in adding pressure so that it is quite fit for anti-deviation 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

It can recruit the pressure lost in slide drilling and overcome the difficulty in deviation control and drilling fast.
