| 摘 要： | 裸眼取换套管工艺是随着油水井老井及腐蚀损坏而开展的一项新的工艺技术。钻井二公司运用该项技术成功地取换修复了因套管腐蚀老化而停产的５口油水井。在取换套管施工过程中，对工具的配套准备、套管割铣工艺及套管回接技术等进行了应用研究，取得了良好的效果。５口井经试压达到了甲方设计要求的，均已恢复了注水及采油生产。

| Abstract: | The technology of borrowing & changing casing at open hole interval is developped with the casing corrosion and failure in oil well and water injection well. Using this technology, borrowing & changing casing of 5 of f production wells were successfully finished by Drilling Company No. 2. In the operation process,the tool matching preparation,the technology of casing cutting and milling and the casing tieback are researched. By the pressure test, 5 wells reached to the design demand of the client and recovered the production and water injection. |
