摘要： 通过Brookfield粘度测定及室内岩心驱油试验评定,研究了聚(丙烯酰胺－丙烯酸)/聚(丙烯酸胺－二甲基二烯丙基氯化铵)[P(AM－AA)/P(AM－DMDAAC)]分子复合型聚合物驱油剂的增粘、抗温、抗盐性及其驱油效果.结果表明：聚合物组成一定时,其复合比影响溶液复合增粘效果;复合型聚合物溶液的抗盐性明显优于P(AM－AA)溶液的抗盐性;多价金属离子的加入是提高溶液抗盐性的有效途径.该驱油剂的最终采收率达61.91％.

关键词: 高分子复合溶液, 聚合物驱油剂, 粘度, 采收率

Abstract: The viscosity enhancement, resistance to temperature and salt, as well as the oil recovery rate of poly (acrylamide-acrylic acid)/poly (acrylamide-dimethyldiallylammoniumchloride) [P (AM-AA)/P (AM-DMDAAC)] intermacromolecular complex used for polymer flooding agent were studied by means of viscosity measurement and simulated enhanced oil recovery test.The experimental results show that when AAmolar content in P(AM-AA) is 27-02%, DMDAACmolar content in P(AM-DMDAAC) is 4-59%, and the weight ratio of P (AM-AA) to P (AM-DMDAAC) is 5O/50, the viscosity of complexed solution gets its maxium, 3.5 times high as that of P (AM-AA) solution.Compared to the constituents,P(AM-AA)/P(AM-DMDAAC) complex solution exhibits better tolerance to temperature and salt.The result of simulated enhanced oil recovery test shows that, using P(AM-AA)/P(AM-DMDAAC) complex as polymer flooding agent, the oil recovery rate could reach 61-91 %, being 11.91 % higher than the rate of 50% reached by water flooding.
