SY5273-91《油田注水缓蚀剂评价方法》标准(以下简称“标准”)是原石油天然气总公司1991年7月19日发布,1991年12月1日实施的行业标准.它规定了油田注水缓蚀剂缓蚀性能的室内和现场评价方法,适用于油田注水缓蚀剂的评价.我们在实践中遇到一些问题,现提出来与同行们商榷.(1)标准中3.2和7.2.2采用了滤膜系数法,由于注水系统中已不采用此方法进行注水指标的检 SY5273-91 Standard for Evaluation Method of Waterflooding Corrosion Inhibitor (hereinafter referred to as “Standard”) is the industry standard implemented by former CNPC Corporation on July 19, 1991 and implemented on December 1, 1991. It regulates oilfield waterflooding Corrosion inhibitor corrosion performance of indoor and field evaluation methods for oil field water injection corrosion inhibitor evaluation. We encountered some problems in practice, are presented to discuss with colleagues (1) the standard 3.2 and 7.2.2 Adopted the membrane coefficient method, because the water injection system has not been using this method of water index test
