●  Non-magnetic equipments: LWD suspention joint, MWD suspention joint, resistivity joint, measuring sub, HCIM sub, pulse generator HOS and non-magnetic X-over

●  Hydraulic thruster: a new type of downhole bit pressure-exerting tool, which using the pressure drop of circular drilling fluid at bit nozzle to exert pressure to drilling bit, hereby realize accurate pressure-exerting and uniform drilling, without consuming any extra energy. The application of hydraulic thruster can not only solve the problem of drilling pressure loss in horizontal wells, extended reach wells and slimhole wells, but also effectively control well deviation, damp&anti-bounce, improve the ROP, and extend bit’s life. It is a practical tool in oil-drilling process with low-cost, easy-operation and significant effect

●  Insulating joint: key technology of transmitting loging signal through electromagnetic wave. It be connected between the non-magnetic drilling collar and drilling pipe. It has two parts, the upper and the lower, which screw together, and can stand drilling torque. One part is insulated from another

●  API Joint: Drilling Rod Joint, Adaptor, Direction Joint, Special Joint and other joint product
