一、前言输、配水、注水管道在油田管道建设占有不小的比例,经调查油田内的输水、供水、注水管线都普遍存在不同程度的内腐蚀。钢管腐蚀表现是局部金属腐蚀穿孔漏水,(见照片)铸铁管表现为红水、内壁结垢引起输水能力衰退甚至堵塞管道,内腐蚀严重的供水、注水管 I. INTRODUCTION Transportation, water distribution and water injection pipelines occupy a large proportion in the construction of oilfield pipelines. Internal water corrosion, water supply and waterflooding pipelines within the surveyed oilfields are commonly found in varying degrees. Corrosion of steel pipe is localized metal corrosion Perforated water leakage, (see photo) Cast iron pipe showed red water, the inner wall fouling caused by the decline of water transport capacity or even plug the pipeline, the serious corrosion of water supply, water pipes
