摘　　要：位于新疆塔里木东河塘油田的 DH4- 8井是目前国内裸眼侧钻点最深、裸眼井段最长的定向开发井。从工程设计、造斜点的选择、现场施工、钻井参数等方面讨论了超深侧钻井的技术要点以及现场施工的规律 ,对于超深井侧钻施工具有一定的借鉴意义。The DH4-8 well, located at Donghetang Oilfield in Tarim Basin, Xinjiang, is a directional production well with the deepest open hole sidetrack point and the longest open hole section. The sidetrack technical keys in ultra-deep well such as engineering design, selection of the KOP, field operation and drilling parameters are discussed as well as the field operation rules, which can be beneficial to sidetracking operations in ultra-deep wells as reference.
