摘要
HXA7-7定向井在固井过程中发生套管泄漏失效事故。采用体积法进行迟到时间试验,并对套管柱进行测井检查,分析了该定向井套管泄漏的原因。结果表明:HXA7-7定向井套管存在原始缺陷,在固井过程中原始缺陷扩展并穿透井壁,最终导致套管泄漏。
Casing leakage occurred during the cementing process of HXA7-7 directional well.Causes analysis of casing leakage in the directional well were analyzed by late time test of volume method,and the casing string was checked by logging.The results show that the original defects in the HXA7-7 directional well casing.In the process of cementing,the original defects spread through the wellbore and eventually lead to the leakage of the casing.
