表面活性剂提高碳酸盐岩油藏采收率进展

Research Progress of Enhanced Oil Recovery with Surfactants in Carbonate Reservoirs

分析了影响表面活性剂提高碳酸盐岩油藏采收率的主要因素,综述了用于提高碳酸盐岩油藏采收率的阴离子、阳离子、非离子和两性表面活性剂的研究进展,指出了四类表面活性剂的优缺点及各自的适用性,介绍了国外的矿场试验。

Factors affecting enhanced oil recovery with surfactants in carbonate reservoirs were summarized. Anionic surfactant,cationic surfactant,nonionic surfactant and ampholytic surfactant used to increase the oil recovery of carbonate reservoir were extensively researched and the application progress was reviewed. Advantages,disadvantages and feasibility of every surfactant in EOR were pointed out. Abroad field tests were also introduced.
