| 摘 要： | 绥中36-1-G43M井是我国海上油田首次自主实施四级完井的多底分支井,采用的是特殊设计的斜向器侧钻系统,即在主井眼中下入空心斜向器进行上分支侧钻作业,利用定向射孔技术勾通上下两个分支,生产管柱可实现分采.此项技术不仅有效解决了海上平台槽口不足的问题,同时对一些低效井的再利用提供了有效的解决措施,对提高油田采收率、降低开采成本有重要意义,在渤海油田中后期的大规模调整开发中有广阔的应用前景.

| Abstract: | The completion technology for level 4 multilateral well used in SZ36-I-G43M well is the first operation for offshore oil- fields. Specially designed whipstock sidetracking system has been used in this well. Sidetracking operations was carried out when the hollow whipstock was run into the main wellbore. Separately production can be achieved when the branches were feed through with oriented perforating. This technology is not only an effective method to solve the problem of insufficient notch, but also a way for inefficient wells reproduces. This technology is significant for improving oil recovery and reducing exploitation costs in the Bohai Oilfield. with broad application prospects. |
