提高三次采油用聚合物耐温抗盐性的研究进展

Research progress on improving heat tolerates and salt resistance of polymer flooding for enhanced oil recovery

综述了国内外三次采油用五大类驱油耐温抗盐水溶性聚合物的研究现状,提出一种提高聚丙烯酰胺类聚合物耐温抗盐性能的的新方法:即开发一种廉价高效二价金属离子络合剂。分析了二价金属离子络合剂的作用机理,并明确了以后的研究方向。

The research progress of new types for enhanced oil recovery （EOR） of heat and salt resistance polymers at home and abroad is summarized. A new method for improving heat tolerates and salt resistance of poly-acrylamide polymers is proposed as develo- ping an inexpensive and efficient divalent metal ion eomplexing agent. The mechanism of divalent metal ion complexing agent is ana- lyzed and the further study direction is put forward.
