CO2乳液在驱油过程中能够有效控制CO2流度, 大幅改善CO2驱油效果, 提高采收率。选择AOT作为CO2乳液用表面活性剂, 通过TRACKER-H界面流变仪测定AOT水溶液与CO2体系在不同温度压力条件下的界面特性, 通过岩心实验测定不同温度压力条件下CO2乳液的封堵和调剖分流效果。结果表明:随着压力的增大, CO2乳液界面张力随之降低, 界面黏弹性随之增大; 随着温度的增加, CO2乳液界面张力增加, 界面黏弹性降低; 温度越高越不利于乳液的封堵, 压力越高越有利于乳液的封堵, 这与体系界面特性研究所得的结果相对应, 说明CO2乳液的封堵效果与其界面特性有关; 温度和压力通过影响CO2乳液的界面特性从而影响其渗流特征, CO2乳液的强度越高、体系界面张力越低、界面黏弹性越好, 其分流效果也会越明显。
