- 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.
