高分子破乳剂及其在大庆油田的应用实验

Macromolecule mmulsion breaker and it’s application test in Daqing oil field

本文综述了中老油田采出液性质的变化和高含水采出液的油水分离特性 ,探讨了聚醚型破乳剂和高分子破乳剂在高含水采出液状况下的适应性。通过理论分析和大庆两个联合站的现场实验证明 ,高分子破乳剂特别适用于高含水采出液的事实 ,并指出了其适应性和提出了其质量与适应性的评价方法。

The changes of properties of the producted liquid and the separation characteristics of oil and water in middle or old aged oil field are depicted in this paper At the same time, it discusses the adaptability of polyaether emulsion breaker and macromolecule emulsion breaker for the producted liquid with high water holdup This study points out the fact that macromolecule emulsion breaker is especially fit for the producted liquid with high water holdup by theoretical analysis and site test in two combined stations of Daqing Also it points out it's adaptability and puts forwards the method to evaluate it's quality and adaptability
