摘　　要：胜和1井浅层变质岩片理发育,钻进过程中易发生井斜,在分析其原因的基础上,在二开井段采用了偏轴与柔性钟摆钻具组合钻进、三开井段采用了单弯动力钻具组合复合钻进,不但有效地防止了井斜,使井眼轨迹符合设计要求,而且大大提高了机械钻速,经济效益和社会效益非常显著,也为大段易斜地层钻进提供了一种控制井斜的新方法。Based on the analysis of the reasons of hole deviation, using eccentric shaft combining with flex pendulum drill assembly in second spud drilling and single bend dynamic drill assembly in third spud drilling can not only effectively prevent hole deviation to make the well trajectory meet the designing requirements but also greatly improve penetration rate. Its economic and social benefits are very remarkable, meanwhile, it also provides a new method for controlling hole deviation in crookedhole formation.
