开窗侧钻及相关配套技术在陆丰13-1油田的应用

Casing Sidetracking and Application of Related Matching Technologies in Lufeng 13-1 Oilfield

陆丰13-1油田13H井是一口裸眼长、水平位移大、多目标的套管开窗侧钻水平井。针对13H井的特点,介绍了从井的工程设计、施工难点分析到实施的工艺流程、技术措施及施工工程中出现的问题。通过开窗侧钻及相关配套技术在13H井的成功实施,解决了无法修复的老井再利用的问题,节约了时间和成本,同时也增加了油田的可采储量,提高了油田的整体开发效率,为海上油田的同类型井的实施提供了宝贵经验。

Well 13Hin Lufeng 13-1Oilfield was a casing sidetracking horizontal well with long open hole,large horizontal displacement and multi objects.According to the features of Well 13H,the well engineering design and difficulties in field operation,the technical processes,technical measures and problems in operation were introduced.Through the successful application of casing sidetracking and related matching technologies in Well 13H well,the problem of reuse of old wells which are hard to be repaired is solved,it saves the operation time and cost,increases the recoverable reserves of the oilfield,improves the efficiency of the overall development of the oilfield.It provides valuable experience for operation in the similar wells of offshore oilfields.
