油田新区开发时,应仔细研究注入水后潜在的地层结垢问题.室内对以高矿化度、高含钡(>1000ppm)地层水为特征的北海油田注水开发过程中结垢和防垢的几个方面进行了研究,结果表明:应采用某一新技术处理海水(注入水)降低SO_4~(2-)含量从而达到防止BaSO_4结垢.
In the development of a new oilfield, the potential fouling of the formation after the injection of water should be carefully studied, and the fouling and scaling of the North Sea oilfield during the waterflood development characterized by high salinity and high barium content (> 1000ppm) Several aspects were studied. The results show that seawater (injected water) should be treated with a new technology to reduce the content of SO 4 2- so as to prevent BaSO 4 fouling.
