【摘要】：近年来纳米技术使得传统油气开采方法悄然转型,针对泡沫流体稳定性差等问题,研究者们提出加入纳米颗粒对泡沫系统进行稳定。本文详细介绍了部分疏水型和亲水型两种类型纳米颗粒稳定泡沫机理的异同,阐述了纳米颗粒在气液界面的不可逆吸附是稳定泡沫的主要机理;综述了纳米颗粒稳定的泡沫在提高采收率和泡沫压裂液中的最新应用,分析表明纳米颗粒不仅大幅度增加了泡沫的稳定性,并且能提高泡沫驱和压裂液的液体效率;指出了纳米颗粒稳定泡沫的问题在于纳米颗粒与泡沫流体作用复杂、改性的纳米颗粒成本较高、对低孔低渗地层的潜在伤害、缺乏工业化应用等;提出了用亲水纳米颗粒与表面活性剂协同稳泡降低成本、针对不同泡沫性能来优化纳米颗粒与表面活性剂的浓度、将纳米颗粒稳定泡沫应用到非常规油气藏等研究方向,最后展望了纳米技术在石油领域的发展潜力。
[Abstract]:In recent years, nanotechnology has quietly transformed the traditional oil and gas production methods, aiming at the problem of poor stability of foam fluid. The researchers proposed that the foam system should be stabilized by the addition of nanoparticles. In this paper, the similarities and differences of the mechanisms of partially hydrophobic and hydrophilic nanoparticles stabilizing foams are introduced in detail. The irreversible adsorption of nanoparticles at the gas-liquid interface is the main mechanism of foam stabilization, and the latest applications of nanoparticles stabilized foam in enhancing oil recovery and foam fracturing fluid are reviewed. The analysis shows that nanoparticles not only increase the foam stability, but also improve the liquid efficiency of foam flooding and fracturing fluid, and point out that the problem of nano-particle stabilizing foam is that the interaction between nanoparticles and foam fluid is complex. The cost of the modified nanoparticles is high, the potential damage to low porosity and low permeability formation, and the lack of industrial application, etc. According to the different foam properties to optimize the concentration of nanoparticles and surfactants, the application of nano-particle stabilized foam to unconventional oil and gas reservoirs is discussed. Finally, the development potential of nanotechnology in oil field is prospected.
