低渗透油田注入水深度处理技术及应用

Low permeability oil field injection water depth processing and application

油田注入水富含硫酸根离子,地层水富含钡锶离子,由于两种水质的不配伍性,形成酸碱不溶的硫酸钡锶垢,常规的注入水处理工艺对硫酸根离子处理效果不明显,采取常规处理+深度处理工艺去处硫酸根离子,防止注入水与地层水结垢,达到提高注采效率。

Oil field injection water is rich in sulfuric acid root ion,formation water is rich in barium strontium ions,as a result of the two kinds of water incompatibility,the formation of acid-base insoluble barium sulfate strontium scale,conventional injection water treatment technology for sulfuric acid root ion treatment effect is not obvious,adopts the conventional treatment and depth process for sulfuric acid root ion,prevent injection water and formation water scale,to improve the injection?efficiency.
