Abstract

High-internal-phase water-in-oil (W/O) emulsions generated in situ have garnered considerable attention as novel profile control systems. However, conventional emulsifiers are unreactive and poorly dispersed in water, necessitating large dosages and resulting in poor injectivity. In this study, we synthesized amphiphilic nanoparticles (SiO₂-NH₂-DAC NPs) containing amine and long-chain alkyl groups using a one-pot method and investigated the stabilized emulsion properties. Our results indicated that W/O emulsions with a water-to-oil ratio (WOR) of 7:3 to 8:2 could be prepared with just 0.1 wt% of SiO₂-NH₂-DAC NPs under neutral and basic conditions, with demulsification occurring under acidic conditions (pH = 2.1), demonstrating the pH-responsiveness of the W/O emulsions. The emulsion viscosity increased from 150 to 2555 mPa·s at different WORs. An additional 18.7% oil recovery was achieved using SiO₂-NH₂-DAC NPs in a heterogeneous core, highlighting their potential as a promising profile control candidate.

利用两亲性纳米粒子乳化剂开发和应用高内相水包油乳剂。

原位生成的高内相油包水（W/O）乳化液作为新型剖面控制系统受到广泛关注。然而，传统的乳化剂在水中缺乏活性且分散性差，因此必须使用大量乳化剂，导致注入效果不佳。在本研究中，我们采用一锅法合成了含有胺和长链烷基的两亲纳米粒子（SiO2-NH2-DAC NPs），并研究了其稳定乳液的特性。结果表明，在中性和碱性条件下，仅用 0.1 wt% 的 SiO2-NH2-DAC NPs 就能制备水油比（WOR）为 7:3 至 8:2 的 W/O 型乳液，在酸性条件下（pH = 2.1）会发生破乳现象，这证明了 W/O 型乳液的 pH 响应性。在不同的 WORs 条件下，乳液粘度从 150 mPa-s 增加到 2555 mPa-s。在异质内核中使用 SiO2-NH2-DAC NPs 实现了额外 18.7% 的采油率，凸显了 SiO2-NH2-DAC NPs 作为有前途的剖面控制候选物质的潜力。

期刊介绍： Polymers (ISSN 2073-4360) is an international, open access journal of polymer science. It publishes research papers, short communications and review papers. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Polymers provides an interdisciplinary forum for publishing papers which advance the fields of (i) polymerization methods, (ii) theory, simulation, and modeling, (iii) understanding of new physical phenomena, (iv) advances in characterization techniques, and (v) harnessing of self-assembly and biological strategies for producing complex multifunctional structures.
