连续油管负压解堵技术在海上油田的应用

Research on the application of coiled oil pipe negative pressure plugging technology in offshore oil field

目前连续油管负压解堵技术被广泛地应用在海上油田,该项技术的应用能够对底层堵塞物进行处理,可以辅助非酸化学药剂的溶解,减少进井处存在的污染问题,真正实现水井的降压增注。本文就连续油管负压解堵技术进行了细致分析,阐述了其在海上油田中的具体应用,以期为海上油田相关工作的开展提供参考。

At present,the technology of coiled oil pipe negative pressure plugging is widely used in offshore oil fields.The application of this technology can treat the underlying blockage,which can assist the dissolution of non-acid chemical agents,reduce the pollution problems existing in the well inlet,and truly realize the step-down and injection of Wells.In this paper,the technology of continuous tubing negative pressure plugging is analyzed in detail,and its specific application in offshore oil field is expounded,which provides reference for the related work of offshore oil field.
