| 摘 要： | 汶川地震断裂带科学钻探1号孔（WFSD-1）发生的孔内事故钻具无法进行处理，需进行定向钻进（侧钻）绕过事故钻具，用LZ-89型连续造斜器在580．07m水泥孔底上侧钻，用3h20min造斜进尺3m就偏出新孔转入正常钻进。介绍了该次定向钻进（侧钻）的技术要点。

| Abstract: | In the complicated formation, 2 drill strings were broken in the hole WFSD - 1 and 2 fishers were lost in it. Directional drilling was conducted to pass by the accident drilling tools. LZ - 89 continuous whipstock was used for sidetracking at the bottom of the cement hole with the depth of 580. 07m. A new hole was generated after 3m directional drilling in more than 3 hours. The paper introduced technical points of the directional drilling （sidetracking）. |
