安塞油田套损井长效防治工艺技术

随着油田开发时间的延长，油水井套损问题日益突出，成为制约油田稳产和高效开发的不利因素。近年来，安塞油田通过大量室内和现场研究，不断探索套管损坏机理和有效治理对策，逐步形成了针对不同套损类型的“以防为主、舫治结合”的套损井长效治理工艺，并取得了良好的治理效果和效益，对安塞油田后期开发中有效解决油水井套损问题提供了积极的指导。

Long-term Prevention and Protection Technology of Casing Failure in An' sai Oilfield

With the development of oilfields,the problem of oil wells casing failure have become increasingly prominent,and become an unfavorable factor in the stable and efficient development of oilfields.In recent years,with a lot of indoor and on-site researches,after exploring casing damage mechanism and effective management measures,we have developed a series of long-term prevention and protection technologies against different types of casing failure wells,and have made good results and returns which is a good help for solving casing failure problems in the latter part of the development in An'sai oilfield.
