Abstract

The results of an experimental study of the interfacial tension and surface wettability in the nanosuspension/oil/rock system are given. The effect of the concentration and size of silicon oxide nanoparticles on the coefficient of interfacial tension and the contact angle of wetting has been systematically studied for the first time. A wide range of weight concentrations of nanoparticles (from 0 to 1 wt %) and their average sizes (from 5 to 50 nm) are considered. It is established that the use of nanosuspensions makes it possible to radically change the wettability of rocks with respect to oil. In this case, this effect depends substantially on the concentration and size of nanoparticles.

纳米氧化硅的添加对岩石润湿性影响的实验研究

摘要

给出了纳米悬浮液/油/岩石系统中界面张力和表面润湿性的实验研究结果。首次系统地研究了氧化硅纳米粒子的浓度和大小对界面张力系数和润湿接触角的影响。考虑了宽范围的纳米颗粒的重量浓度(0至1重量%)及其平均尺寸(5至50 nm)。可以确定的是,使用纳米悬浮液可以从根本上改变岩石相对于石油的润湿性。在这种情况下,这种效果主要取决于纳米颗粒的浓度和大小。
