随着油田开发进入中后期,由于液体腐蚀等因素造成油水井套管强度降低,再加上油层压力变化,修井作业过程中外力作用以及油藏本身条件变化等各种因素的影响,就会发生变形、破裂、错断等损坏,对油田开发后期注采造成巨大影响,本文笔者参与了多口井的套管修复工作,其中的工具选择、大修方案的制定等供大家参考学习。
As oilfield development enters the middle and late stages, due to factors such as liquid corrosion, the casing strength of oil and water wells is reduced, together with the influence of various factors such as the change of reservoir pressure, the external force during workover and the change of reservoir conditions Deformation, rupture, fault and so on, which have a huge impact on oil and gas injection and production in the late stage of oilfield development. In this paper, I participated in the casing repair work of many wells, including tool selection and overhaul plan formulation for reference.
