| 摘 要： | 在易斜地层钻进时，带扶正器的防斜钻具组合的防科效果往往不甚理想。通过不断的实践和摸索，发现柔性钟摆钻具组合可取得比较满意的效果。其特点是钟摆力强、防斜降斜效果好，而且可在常压下钻进，既保证了井身质量又提高了机械钻速。文中对其防斜、纠斜机理及应用概况作了简短的分析，并提出几点结论和建议。

| Abstract: | The results of inclining-prevention drilling assembly with stabilizers are not so ideal during drilling decimated formations.By continuous practices and study, flexible pendulum string assembly has been found more satisfactory. The advantages of the tools include:strong pendulum force,good inclining-prevention and dropping results,which ensure the wellbore quality and improve ROP.The paper analyses brieny the mechanism and the applications, and puts forward some conclusions and suggestions. |
