In Fukang area of Junggar Basin, the deep strata exhibits high rock hardness and large dip angle, rendering traditional pendulum drilling assembly speed-up tool ineffective in preventing deviation and achieving fast drilling. To address this challenge, this paper, based on the analysis of the mechanical drilling rate improvement achieved by employing a torque impactor in hard formations, introduces a novel Bottom Hole Assembly (BHA) configuration that combines a Torque Impactor with a Single Bend Screw. This innovative BHA is designed to maximize the release of drilling pressure and leverage the speed-up capabilities of the torque impactor while effectively controlling deviation in high-angle formations. Based on the equilibrium trend analysis, this study investigates the influence of BHA structural parameters on its anti-deviation capabilities, and identifies key parameters. The field application shows that the newly designed BHA (Bottom Hole Assembly), integrating torque impactor with Single Bend Screw, can effectively realize the purpose of anti-deviation and fast drilling in hard formation, providing valuable insights for drilling operation in deep, hard formation.
