| 摘 要： | 对反井钻井施工过程中影响导孔偏斜的两大根本因素：导孔三牙轮钻头与非均质各向异性地层相互作用时受力不平衡和导孔钻进时下部钻具组合受压发生弯曲变形进行了详细的分析和研究。在此基础上建立了其相关的计算模型。

| Abstract: | There are two basic factors affected to the pilot hole deflection during a raise boring. The paper has a detailed analysis and study on the unbalanced stress during the interaction between three cone bit non homogeneous all directional different rocks and the bending and deformation of the bottom drilling tools during the pilot hole drilling. Base the above, a related calculation mode was established. |
