中文摘要: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580.07 m水泥孔底上侧钻，用3 h 20 min造斜进尺3 m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。

Application of Directional Drilling Technology in the Hole WFSD-1 of Wenchuan Earthquake Fault Scientific Drilling Project
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).
