套破井修复技术适应性分析

Adaptability analysis of casing breakage repair technology

本文通过对某油田近5年修复的套破井进行统计,分析了不同套破修复技术对套破井的适应性。为了综合反映套破修复技术的经济性,对单一技术指标进行了无量纲处理,并提出了经济系数的概念。分析表明,经济系数基本反映了套破修复技术的经济实用性。对于套管破漏井,适应性最好的修复技术是注灰封堵技术,其次是套管补贴技术。

Through the statistical analysis of repaired wells on a field of nearly five years,this paper analyzes the adaptability of different casing breakage repair technology.In order to comprehensively reflect the economy of casing repair technology,the dimensionless treatment of a single technical index is carried out,and the concept of economic coefficient is put forward. The analysis shows that the economic coefficient basically reflects the economic practicability of casing repair technology. For casing breakage wells,the most adaptable repair technology is ash injection plugging technology,followed by casing subsidy technology.
