| 摘 要： | 元坝区块油气井超深及高温高压特征明,开发难度大。对元坝2井的修套施工证明,该区域井下情况复杂,套磨铣修复套管非常困难且成本高昂。对该区块的后续开发,建议采用加厚套管封堵盐膏层;进行地层测试时必须充分考虑套管保护措施;对似类似元坝2井的套管错断情况,建议采取开窗定向侧钻工艺修复,放弃修套施工。

| Abstract: | The oil and gas wells in Yuanba Area are extra deep and have obvious features of high temperature and high pressure,which results in exploitation with great difficulty.The workover construction of Yuanba-2 Well shows that the downhole situations in this area are complicated and that repairing casing by casing milling is too difficult and expensive.As for the follow-up development in this area,the authors suggest thickening casing blocking salt cream,and taking casing protection measures into full considerat... |
