摘要： 选用相对分子质量在( 1. 6~1. 9) 暳1 0 7 的S N F 3 6 4 0 D聚合物, 测试了该种聚合物在天然低渗透岩心上的流动性、 岩心孔隙中的黏度、 与甜菜碱表面活性剂二元体系的界面张力以及驱油效率。结果表明, 该种聚合物在天然低渗透油层上有较高的阻力系数与残余阻力系数, 表现出良好的注入性能和流度控制能力; 在岩心孔隙中的黏度损失率低于低分子质量7. 0暳1 0 6 聚合物; 其甜菜碱二元复配体系与原油间的界面张力能够达到极低( 1 0-3mN / m) 。通过天然低渗透岩心上的驱油实验可知, 该种聚合物单独聚驱的化学驱采收率达到7. 8 5%, 与其复配的甜菜碱二元体系的化学驱采收率达1 4. 7 5%左右, 远远高于低分子质量7. 0暳1 0 6 聚合物的采收率。因此, 该种聚合物与低渗透油层有较好的匹配性, 对低渗透储层的开发具有一定的指导性。

Abstract: Selection of relative molecular weight was about 1.6×107 to 1.9×107 SNF3640D polymer，Lab researches were carried out on its mobility，viscosity of core porosity，the interfacial tension of the binary combination with betaine surfactant compound system could achieve ultra low and recovery factors. The results show that higher coefficients of resistance and residual resistance are obtained in low permeability layers. Better injection and mobility are demonstrated by the polymer; the viscosity loss rate of this polymer is lower than traditional 7.0×106 low molecular polymer; the combination of the betaine surfactant compound system can attain the ultralow interfacial tension with the oil (10-3 mN/m). Moreover, the chemical flood recovery efficiency of this polymers flooding alone on a natural rock could reach about 7.85 percent, the compound system could reach about 14.75 percent ,which is far higher than traditional polymer of 7.0×106, therefore, this kind of polymer with low permeability reservoir has good matching, it has a certain guidance for low permeability reservoir development.
