摘要: 泡沫压裂液凭借低含水、易返排、携砂能力强、对储层伤害小等优点,成为非常规油气藏开发的关键技术之一。但泡沫的衰变问题严重影响了压裂的增产效果,随着纳米技术的发展,加入纳米颗粒提升泡沫压裂液的性能已成为研究热点。为此,介绍了纳米颗粒对泡沫压裂液稳定性、携砂性、降滤失性、伤害性的影响研究进展。并指明了下步研究方向,主要在利用机器学习算法和统计模型全面考虑各因素对泡沫稳定性的影响,加深纳米颗粒与表面活性剂的相互作用机制的认识,研发低成本高效纳米颗粒,降低纳米颗粒对储层的伤害,提高纳米泡沫压裂液在复杂储层环境下的稳定性和分散性等方面开展研究。研究成果可为纳米泡沫压裂液在非常规油气藏开发中的应用和发展提供理论参考和技术支持。

Abstract: Foam fracturing fluids, with benefits like low water content, easy flowback, strong sand-carrying capacity, and less reservoir damage, are a key technology for unconventional oil & gas reservoir development. However, foam decay greatly affects the stimulation by fracturing.With nano-technology progress, adding nanoparticles to boost foam fracturing fluid properties has become a research hotspot. This paper introduces the research progress of nanoparticle impacts on stability, sand-carrying capacity, fluid loss reduction, and damage reduction of foam fracturing fluids. It also points out future research directions, which mainly involve using machine learning algorithms and statistical models to holistically assess factors influencing foam stability, deepening the understanding of nanoparticle-surfactant interactions, developing low-cost and efficient nanoparticles, reducing nanoparticle-induced reservoir damage, and enhancing the stability and dispersion of nano-foam fracturing fluids in complex reservoir environments. The research findings can offer a theoretical reference and technical support for the application and development of nano-foam fracturing fluids in unconventional oil & gas reservoir exploitation.

Key words: fracturing fluid, unconventional reservoir, foam, nanoparticles
