套管检测技术在安塞油田的发展及应用

Development and Application of Casing Detection Technology to 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。本文介绍了安塞油田历年所使用过的套管检测技术．评价出了适合安塞油田的套管检测技术。

As extension of the production time, casing pipes are deformed and damaged due to external force and chemical corrosion effect, the casing failure wells are increased year by year, and have become one of factors limiting highly effective development of Ansai Oilficld. It has been a precondition for controlling casing failure wells to judge whether production wells are casing failure wells and to determine the location of casing failures. The paper describes the casing pipe detection technology used by Ansai Oilfield casing over the years and evaluates the casing pipe detection technique suitable for Ansai Oilfield.
