摘　　要：塔里木油田台盆地区241.3mm井眼介于1500～6600m之间,存在井段长、井段位移控制要求高的特点,从而束缚了钻井速度的提高。文章在分析各井段钻井特征的基础上,提出在中下部井段采用预弯曲动力学控移快钻技术方案,在优化设计BHA的前提下进行了一口井的现场试验。结果表明,该方法不但可以较好地控制井斜,而且可以较大幅度提高钻井速度。与邻井相比,试验井段的平均机械钻速比邻井平均机械钻速提高62.1%。The well depth with diameter of 241.3mm hole in Taipen area of Tarim Oilfied is from 1500 m to 6600 m, it is characterized by long well section and high demand of borehole displacement control, so the increase of ROP(rate of penetration) was limited. Based on the analysis of drilling features in each well section, a pre-bending dynamics method was used to control the deviation and bottom hole displacement and improve drilling speed in the middle and lower well section. A field test was done after the BHA was optimized, the results showed that the method could not only control the borehole deviation better, but also increase ROP greatly. Compared with adjacent wells, the average ROP of test borehole section was increased by 62.1%.
