摘要：         对适用于低渗透油藏开发的微乳液配方及性能进行了研究,并以方程系数法为基本方法,通过室内实验确定出适用于朝阳沟低渗透油藏的微乳液配方(质量分数):1%石油磺酸盐+1%正丁醇+1.38%正己醇,测量微乳液特性参数R=0.261,验证配方微乳液为最佳中相体系。使用激光粒度仪对微乳液体系进行粒子半径测量,测量其粒子半径在0.01~0.22μm,适用于朝阳沟油藏微小孔喉。通过微乳液驱替低渗透岩心实验,得到微乳液驱能在水驱采收率的基础上提高最终采收率7.41%,降低注入压力24%,验证了该微乳液体系对朝阳沟低渗透油藏的适用性。

Abstract:

The formula and performance of the microemulsion that is applicable for development of low permeability reservoirs are studied. Based on the method of equation coefficient method, the microemulsion formula suitable for the low permeability reservoir of Chaoyanggou is determined by laboratory experiment as 1% mahogany sulfonate+1% butanol+1.38%

hexanol. The characteristic parameter for measuring the microemulsion is R=0.261. The formula microemulsion is verified as the optimal middle phase system. The particle radius of the microemulsion system is measured by laser particle size analyzer. The particle radius range from 0.01 μm to 0.22 μm which is applicable to micro pore and throat in Chaoyanggou reservoir. It can be found that the microemulsion flooding improves the final recovery efficiency by 7.41% on the basis of water displacement recovery and reduces the injection pressure by 24%. This verifies the applicability of the microemulsion system for the low permeability reservoir of Chaoyanggou.
