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。
DH4-8 well located in East Hetang Oilfield in Tarim, Xinjiang is the most developed directional drilling well with the deepest open hole and the longest open hole in the country. The technical points of super deep drilling and the rules of on - site construction are discussed from the aspects of engineering design, selection of incline, site construction and drilling parameters, which will be of reference significance for the construction of sidetrack in ultra - deep wells.
