摘要： 根据油藏精细描述在对彩南油田三工河组油藏剩余油储量现状及分布特点认识的基础上,优选了水平井布井区块,论证了水平井可行性, 优化了井位设计。在现场钻井过程中,采用综合录井、岩屑录井以及三维地质模型等多种技术手段实时监控,成功实现了断裂绕障施工,并达到了较高的油层钻遇率。投产后水平井产量达到了方案设计产能,取得了良好的经济效益。彩南油田断裂绕障水平井的成功实施, 为挖潜断块底水油藏剩余油开辟了广阔的空间。

Abstract: Based on the status and distribution characteristics of the remaining oil and reserves of Sangonghe reservoir in Cainan oilfield, the block suitable for drilling horizontal well is selected, the feasibility of the horizontal well is demonstrated and the well location design is opti mized. Through real-time control by means of composite log, cutting log and 3D geologic model and other technical methods, the operation for bypassing the fault is realized and higher oil layer drill-encountering rate is achieved successfully. And the productivity by horizontal drilling process after putting into production meets the demand of the project design, obtaining good economic efficiency. The successful implementa tion of this scheme opens up wider spaces for developing the remaining oil in bottom water fault-block reservoirs in Cainan oilfield.

Key words: Cainan oilfield, reservoir description, fault bypass, horizontal well
