海上油田X井隔水管泄漏分析与治理

摘要

为解决海上油田X井隔水管漏气问题,通过环空状态、井况和井下工具性能分析,明确了隔水管漏气原因:9-5/8＂套管密封总成失效导致浅层气窜至隔水管环空,进而由隔水管损坏处泄漏.结合泄漏情况及X井结构特点,优选机械式钢套法对漏点进行修复,成功地解决了该井漏气问题.%In order to solve the problem of leakage of X well in offshore oil field,Through annulus condition,well condition and downhole tool performance analysis,The reason for the leakage of the riser is clearly defined:9-5/8 "sleeve seal assembly failure causes shallow gas to move to the riser annulus. Then it is leaked from the damage of the riser. Combined with the leakage situation and the structure characteristics of X well,The mechanical steel sleeve method is optimized to repair the leakage point, which successfully solves the problem of gas leakage in the well.
