随着国内外油田开发年限的日益增长,注水井浅层套漏问题日益严重,加剧了油田注采井网的不完善程度,影响油田开发效果。本文重点分析了注水井浅层套漏的原因,包括地质、腐蚀、套管本身以及施工作业等原因,为套漏的治理提供依据。 With the growing number of oilfield development years at home and abroad, the shallow leakage of water injection wells is increasingly serious, exacerbating the imperfection of oil and gas well pattern and affecting the oilfield development effect. This paper focuses on the causes of casing leakage in shallow wells, including reasons of geology, corrosion, casing itself and construction operations, and provides the basis for the control of casing leakage.
