摘　　要：本文提出了一种由微观结构改善剂(MSI)和微观油水流度比改善剂(MMI)组成的"双微改善"复合调驱体系(BMIS),可同时改善储层微观结构和油水流度比。主要研究了MSI在模拟水和BMIS中的分散、膨胀特性和微观结构,模拟油与MMI溶液间的界面张力(IFT),MMI溶液对F油田原油的降粘作用。MSI水化膨胀10d后体积膨胀了64倍。在原油-水-MMI体系中形成了水包油(O/W)乳液,油在MMI溶液中呈球形或椭球形分散。MMI达到1600mg·L^(-1)时,MMI溶液与模拟油的IFT降至0.06mN·m^(-1);原油与MMI溶液为3∶7时,原油降粘率达94.97%。本文的研究将有助于双微改善复合调驱体系的进一步优化。A bi-micro-improving composite system(BMIS)consisted of micro-structure improver(MSI)and micro-mobility improver(MMI)was proposed to improve the micro-structure of reservoir and heavy oil-water mobility at the same time. The dispersion morphology, expanding properties and micro-structure of MSI in simulated water,the interfacial tension(IFT)between simulated oil and MMI solution, the viscosity reduction of crude oil by MMI solution. The volume expansion of MSI was about 64 times after hydration expansion for 10 days. In the oil-water-MMI system, water oil oil-in-water emulsion(O/W)is formed, and oil is dispersed as spherical or ellipsoidal particles in the MMI solution. The IFT between MMI solution and simulated oil decreased to 0.06 mN·m^(-1) when the MMI concentration reached 1600 mg·L^(-1). The viscosity reduction rate was up to 94.97% when the proportion of the crude oil from F oilfield and MMI solution was 3∶7. The research of this paper is helpful for the optimization of the bi-micro-improving composite system.
