摘　　要：江苏油田属于复杂小断块油田,在直井段存在打不直、机械钻速慢的现象。常规钟摆钻具组合以牺牲钻井速度和钻井效益为代价来防斜。介绍反钟摆钻具组合防斜打快机理及其钻柱受力分析的影响因素,反钟摆钻具组合受稳定器位置和尺寸的影响。通过江苏油田现场应用情况分析,并与同一区块邻井相同井段没有使用该钻具组合的钻进效果情况对比,实践表明,反钟摆钻具组合解决了防斜打快的瓶颈问题,由于解放了钻压,充分发挥钻头的攻击性,提高了作业效率,缩短钻井周期,使钻直与钻快统一起来。对控制井斜,提高井身质量具有一定的指导意义。Jiangsu Oilfield was a complex small fault block reservoir,in which there existed inclination in the vertical section,low penetration rate.In conventional pendulum assembly the rate of penetration and drilling efficiency were sacrificed for deviation control.The mechanism of inverse pendulum drill-tool assembly the deviation control and rapid drilling and influential factors of force applied on drill strings were summarized.The effect of stabilizer location and size on the inverse pendulum assembly was introduced.Its application in Jiangsu Oilfield was analyzed,contrasted with the nearby wells without using the assembly in same section.The result shows that the inverse pendulum assembly can solve the bottleneck problem of deviation control and rapid drilling,give full play to the attacking drill,improve work efficiency,shorten the drilling cycle,integrate the vertical drilling with rapid drilling.It provides a guidance for deviation control and improve the quality of wellbore.
