吐哈油田套损井现状调查及治理思路

Present Situation and Rectification Measures of Casing Damaged Wells in Tuha Basin

吐哈油田已全面进入高含水低速开发阶段,随着开发程度的加深,油田套损井逐年上升,加大了分层注采结构调整的难度。为此,在对吐哈油田套损井现状进行全面系统调研的基础上,分析了套损井对油田开发效果的影响,并提出了套损井综合治理思路。

Tuha oilfield has entered into a high water - cut stage with low production. As the development degree deepens, the number of casing damages increase year by year, which makes it difficult to adjust the separated - layer injection and production. Therefore, on the basis of comprehensive and systematical study of the present situation of casing damage wells in Tuha basin, the effect of casing damage on oilfield development is analyzed and comprehensive measures to repair casing damage are proposed.
