国内油气田常见套管失效模式及解决思路

Common Casing Failure Modes in Domestic Oil and Gas Fields and Solutions

随着油气田开发的不断深入,非常规油气资源占据着越来越重要的地位,面对种种复杂的地质环境,套管柱服役条件更加恶劣,套管损坏严重、套管成本居高不下等一系列问题日益突出。在对套管服役条件以及失效模式调研的基础上,总结出套管的优化方向,提出了相关的解决方案。

With the continuous deepening of oil and gas field development,unconventional oil and gas resources occupy an increasingly important position.Faced with various complex geological environments,casing string service conditions have become more severe,casing damage is serious,and casing costs remain high.The series of problems have become increasingly prominent.Based on the investigation of casing service conditions and failure modes,this paper summarizes the optimization direction of casing and proposes related solutions.
