摘　　要：准噶尔盆地阜康地区深部地层岩石硬度高、地层倾角大,传统的钟摆钻具组合提速工具防斜打快效果差。针对这一问题,在对硬地层中使用扭力冲击器提高机械钻速效果分析基础上,提出了既能充分释放钻压、发挥扭力冲击器提速作用,又能在大倾角地层有效防斜的“扭力冲击器+单弯螺杆”底部钻具组合(Bottom Hole Assembly, BHA)。基于平衡趋势分析研究了BHA结构参数对其防斜能力的影响,确定了关键参数。现场应用表明,新设计的BHA能有效实现硬地层防斜打快目的,为深部硬地层钻井作业提供了一定借鉴。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.
