摘要
Abstract
During the well repair and inspection operation in a certain oilfield group,it was discovered that the N80 oil pipe in water injection wells failed due to perforation and damage of the pipestring.Analysis revealed that the failure of pipe string was mainly caused by CO2 and H2 S corrosion,while Cl-in the produced water initiated pitting corrosion,accelerating the overall corrosion process and ultimately leading to pipe string perforation.To systemati-cally evaluate the downhole pipe string safety status of water injection wells in Block B of the oilfield group,key pa-rameters such as corrosion rate,residual strength,and minimum load-bearing wall thickness of the water injection well pipe strings were calculated by integrating downhole string information and on-site corrosion conditions,enab-ling a prediction of the remaining life of the corroded pipe strings.关键词
