| 摘 要： | 针对渤海海上稠油水驱采收率较低的问题,研究了疏水缔合型聚合物AP-P4溶液的驱油效果.结果表明:随着原油黏度的增加,水驱和聚合物驱的采收率均降低；采收率增幅先降低后增加再降低.原油黏度在100～300mPa-s时,AP-P4聚合物采收率增幅大于7％.随着AP-P4溶液浓度增加,剪切后溶液的阻力系数Fr和残余阻力系数Frr逐渐增加,Frr可达2.3～14.5,在高渗透多孔介质中建立高渗流阻力的能力较好.可以降低AP-P4溶液在稠油油藏聚合物驱中所需的溶液黏度,有助于降低聚合物溶液的浓度.在渤海典型稠油油藏的现场试验取得了明显的降水增油效果,为缔合型聚合物提高高渗稠油油藏的采收率提供了理论和应用依据.图3参5
