本文通过对葡萄花油田北部一断块地区套损井的分类分析,研究了套管损坏井在纵向、横向及套损类型上的分布规律,重点探讨了油水井套管损坏形成机理,并对历年来发现的套损井进行了机理研究,并提出了相应的防治对策,为今后套损防护工作提供了理论依据。 Based on the classification analysis of casing damage in a fault block in the northern part of Putaohua Oilfield, the distributive law of casing damage in the longitudinal, lateral and casing damage types was studied. The formation mechanism of casing damage in oil well was discussed. The casing damage discovered over the years has been studied in terms of mechanism, and corresponding prevention and control measures have been put forward, providing a theoretical basis for future casing damage prevention work.
