摘要
分子膜降压增注技术是将分子膜剂注入到石油储层微孔道中来改变孔壁润湿性及微结构特性,达到降低注水压力或提高注水量的目的。研究了分子膜-壁的微观引力与水-壁微观引力的对比,认为分子膜在竞争吸附中占优势,能够突破并赶走水化层,最终牢固吸附在孔壁上,形成分子膜层;并探索了分子膜剂应用条件,对分子膜剂吸附量的变化规律进行了研究,同时从降低边界层效应和注水摩阻两方面揭示了分子膜剂减阻机理,最后进行了分子膜剂减阻性能研究。
The wettability and microstructure characteristics can be changed by molecular film technology through injecting molecular film reagent into the reservoir micro pores, and the purpose of reducing injection pressure and improving water injection total is achieved. The adsorption capacity comparison between molecular films to rock surface with water molecular to rock surface was studied, and it was revealed that the molecular film took advantage in competition, then adsorbed in rock surface and formed molecule layer. Based on it, the application conditions and its change rules were explored then the molecular drag reduction mechanism from reducing the boundary layer effect and friction was revealed. At the last the property of the molecules film drag reduction was studied.
