混合油相纳米复合胶束微乳液稳定机理及微孔道流动效应

The deep and unconventional complex formation, and their rich nano-micron meter channels will be regarded as the important resources of enhancing oil and gas yield. Creating novel microemulsion for such microchannels will be of significance in prospective innovation and urgent requirements..The sol-gel reaction process of nanomaterial’s precursors is designed and the nanoscale nucleation process is optimized. Then, several topological surface nanoparticles such as coarse, porous, multilayer and clusters, etc. are prepared. By their surface reactive hydroxyl groups, the nanoparticle’s surface grafting, cross-linking and encapsulation modifications are made. Then, a series of multi-functional nanocomposite emulsifiers are prepared. They apply to tuning blend oil nanocomposite micelle morphology, microemlusions and their viscosity. Based on this principle, the residual oil is specially separated into several fractionations of different polarity, molecular structure and molecular mass while mixed into blend oil phase. So, the residual oil nanocomposite micelles and their micro-emulsion of very high temperature tolerance are prepared..Furthermore, several channel type cores and ion etching micro channel cores are made. On the cores, the microemulsion permeation, seepage and fluid conductivity performance experiments through micro-channels will be established. Then, these nanocomposite microemulsion’s tunable flow behavior and their multi-functional application methods are explored..By using extremely rich natural resources of layered minerals and solid material foundation of residual oil, a series of novel nanocomposite emulsifiers, residual oil nanocomposite micelle and their high temperature tolerance microemulsions will be prepared. They apply to creating multi-functional flow and enhancing oil and gas fluid effects in the complex formation and its microchannels. This has high significance in resources recycling and reusing, and in important science and technology.
