Hydraulic Thruster Type TLQ
Model “TLQ” Hydraulic thruster can change the pressure drop of bit nozzle or down-hole motor into drill pressure, not only can solve the problems that drill pressure is difficult for appling in directional well, horizontal well, but also has the acting of heave compensator in off-land drilling. And it can be capable of improving the stressed state of drilling tool and reducing fatigue damage of drilling tool, and also increasing the drilling rate.
