目前海塔油田套损井逐年增多,油水井套损形态以单井多点变形为主,修复工艺为整形扩径。2009年对4口套损变形井进行整形扩径,8个月后复查发现重复套变。本文针对这一问题,对现行套损变形井修井方法进行对比分析,最终优选出适合海拉尔油田的修井方法,为今后变形井修复提供了依据。 At present, the casing damage wells in Haita oil field have been increasing year by year. The casing damage patterns of oil and water wells are dominated by single-well multi-point deformation, and the repair process is plastic expansion. In 2009, 4 sets of casing deformation and deformation wells were expanded and expanded, and 8 months later, they were found to have repeated casing changes. Aiming at this problem, this paper compares and analyzes the current well method of casing deformation and deformation well workover, and ultimately optimizes the workover method suitable for Hailaer oilfield, which provides the basis for the future deformation well repair.
