套管检测技术在安塞油田的发展及应用

Development and application of casing damage detection technology in Ansai oilfield

随着生产时间的延长,套管受外力、化学腐蚀的作用引起变形、损坏,套损井的数量逐年增加,成为制约安塞油田高效开发的因素之一。判断生产井是否套损并确定套损位置成为治理套损井前提条件。文章介绍了安塞油田历年所使用过的套管检测技术,找到了适合安塞油田的套管检测技术。

With the extension of production time,and casings are distorted and damaged due to many factors such as external forces、chemical corrosion,the casing damaged wells have increased year by year which has been one of key factors that restricts Ansai oilfield's high-efficient development.Therefore,it has become a prerequisite for controlling well casing damage to judge whether producing wells are damaged and to determine the location of casing damage.This paper introduces the casing inspection technologies that once used in Ansai oilfield and evaluates the casing detection methods that fits for Ansai oilfield.
