摘　　要：泡沫流体作为一种非牛顿流体,广泛应用在石油工业的钻井、油气井增产、修井、提高采收率等各个方面。纳米颗粒作为一种新兴的稳泡材料,可以明显提高泡沫的稳定性。本文分别从纳米颗粒与界面的相互作用、单一疏水颗粒稳泡影响因素、以及亲水颗粒与表面活性剂协同稳泡三个方面来阐述纳米颗粒在稳泡方面的机理,最后探讨了纳米颗粒在稳泡方面的前景以及研究方向。As a kind of compressible non-Newtonian fluid, foams have been widely used in drilling, stimulation of wells, well workover, EOR and so on. Nanoparticles, as an emerging material to stabilize foam, can significantly improve the stability of foam. In this paper, the mechanisms of the nanoparticles in the foam stability was mainly discussed from three aspects, including the interaction between nanoparticles and interface, influencing factors of single hydrophobic particles in stabilizing foams, synergistic stabilization of foams by a mixture of hydrophilic nanoparticles and surfactant. In addition, the prospects and direction ofnanoparticles for stabilizing foams were also discussed.
