For years of technical innovation and field practice, high-deviated well and horizontal well drilling have been developed in a boom, forming a series of special technologies, including ultra-deep directional drilling, horizontal well drilling against complex geology, horizontal well and multilateral well drilling in low-pressure, low-permeability and low-productivity gas reservoir. Related techniques have been accordingly developed, inclusive of MWD under high temperature, underbalanced horizontal well configuration and trajectory design, torque-drag and well trajectory management for long lateral, MWD for gas drilling, sidetrack for multilateral well, etc. Ultra-deep directional drilling and underbalanced (gas) horizontal well drilling take the leading position in China.
