【摘要】 为评价"SJT-B表面活性剂/聚合物"二元复合体系的性能,利用现代物理模拟方法,将"碱/表面活性剂/聚合物"三元复合体系和聚合物溶液分别从流动性质、传输运移能力和驱油效果等3个方面,与之进行对比.结果表明,在相同聚合物质量浓度条件下,与三元复合体系和聚合物溶液相比较,"SJT-B表面活性剂/聚合物"二元复合体系的阻力因数和残余阻力因数较大,在多孔介质内传输运移能力较差,调整吸液剖面能力较强,并且调驱采收率增幅更大.更多还原

【Abstract】 In order to further evaluate the property of SJT-B surfactant/polymer combination system,with the modern physical simulation method,we studied the flow property,transmitting ability and displacement effect of SJT-B surfactant/polymer system,ASP system and polymer solution.The results show that the resistance factor and residual resistance factor of SJT-B surfactant/polymer system is higher,transmitting ability in porous media is poor,ability of profile modification is better and increasing degree of recovery is higher compared with polymer solution under the condition of same polymer concentration.更多还原
