Research Progress on the Application of Nanomaterials in Water Plugging and Profile Control Agents-Review

近年来,随着纳米技术和油田开发技术的不断发展,纳米材料已经被广泛应用于堵水调剖剂中,并取得了不同程度的发展。分别从泡沫、聚合物凝胶、乳液和超细水泥浆四个方面综述了纳米材料在堵水调剖剂中的研究进展和最新成果,并分析了纳米材料在堵水调剖剂中的作用机理及其影响规律。结果表明,在体系中加入纳米材料后,可凭借其尺寸小、表面积大等物理化学特性,与堵水调剖剂发生界面吸附、插层、剥落等相互作用,使堵水剂的稳定性、强度和耐温耐盐性显著提升,从而有效提高堵水率和油田采收率。此外,从堵水剂研发的角度指出了目前这方面研究存在的各种问题,以期对纳米材料在堵水调剖剂中的研究和应用提供参考。

In recent years, with the continuous development of nanotechnology and oilfield development technology,nanomaterials have been widely used in water shutoff and profile control agents and have achieved varying degrees of development.This article reviews the research progress and latest achievements of nanomaterials in water shutoff and profile control from four aspects: foam, polymer gel, emulsion, and superfine cement slurry, and analyzes the use of nanomaterials in water shutoff and profile control agents. The mechanism of action and its influence on the law. It is found that after adding nanomaterials to the system, it can interact with the water shutoff profile control agent by its physical and chemical properties such as small size and large surface area so that the stability, strength, and strength of the water shutoff agent can be improved. The temperature and salt resistance is significantly improved, thereby effectively improving the water shutoff rate and oilfield recovery rate. In addition,from the perspective of water shutoff agent research and development, various problems in current research in this area are pointed out, to provide a reference for the research and application of nanomaterials in water shutoff profile control agents.
