摘要
Abstract
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.关键词
