中文摘要:
      水基纳米流体具有很好的适配性,能够进入渗透率低的油藏储层发挥特有的功效。采用硅烷偶联剂法改性纳米二氧化硅,优选分散剂制备了功能纳米二氧化硅流体分散液(0.05wt%改性纳米+0.01wt%APE-X)。利用动态光散射粒度仪分析了改性纳米粒度主要分布20~30nm,且澄清透明。通过润湿吸附测试、降压增注、渗吸物理模拟实验考察纳米流体分散液的性能。结果表明,改性纳米颗粒可以分散吸附在岩石壁面,从而改变岩石的润湿性,“滑移效应”让注入流体进入微孔道;当注入量不高于0.3PV时,高效地降低注入压力,最高的降压率达到34%,纳米分散液进入储层后具有比常规表面活性剂更好的渗吸排油能力。
英文摘要:
      The water-based nanofluids have good adaptability, and can enter reservoirs with low permeability and play a unique role. Silane coupling agent was used to modify nano-silica, and functional nano-silica fluid dispersion (0.05 wt% modified nano+0.01wt% APE-X) was prepared. Dynamic light scattering particle size analyzer was used to analyze that the modified nanoparticles were mainly concentrated at 20-30 nm, and the dispersions were clear and transparent. The properties of nano-fluid dispersion were investigated by wetting adsorption test, pressure-lowering and injection-increasing, and physical simulation of infiltration. The results show that modified nanoparticles can be dispersed and adsorbed on the wall of rock, thus changing the wettability of rock, and the "slip effect" promotes the injection of fluids into micro-channels. Nanofluids can effectively reduce injection pressure when the injection volume is less than 0.3PV, and the highest pressure drop rate is 34%. The nano-dispersed liquid after entering reservoir has higher oil displacement ability than conventional surfactant.
