Abstract
Изобретение относится к способу получения нанофлюида с нанопузырьками газа и может найти применение в нефтяной промышленности, конкретно, для использования в качестве текучей среды при вытеснении и добычи нефти, особенно при разработке нефтяных месторождений с низкой проницаемостью. Задачей изобретения является разработка способа получения устойчивого нанофлюида и обеспечение эффективного формирования стабильных пузырьков с размером нанометрического диапазона. Поставленная задача достигается тем, что в способе получения нанофлюида с нанопузырьками газа, включающем смешение газа и жидкости, после смешения газа и жидкости в газожидкостной смеси поддерживают давление выше давления насыщения жидкости газом (P). Давление в газожидкостной смеси поддерживают на уровне 1,1-2,0 P. Соотношение объемов газа и жидкости определяют из закона Генри при давлении насыщения жидкости газом. Соотношение объемов газа и жидкости определяют по кривой растворимости газа в жидкости при давлении насыщения жидкости газом. В газожидкостную смесь дополнительно вводят анионный, катионный или неионогенный ПАВ.The invention relates to a method for producing nanofluid with gas nanobubbles and can be used in the oil industry, specifically for use as a fluid for displacing and extracting oil, especially in the development of low-permeability oil fields. The objective of the invention is to develop a method of obtaining sustainable nanofluid and ensuring the effective formation of stable bubbles with a size of nanometric range. The task is achieved by the fact that in the method of producing nanofluid with nanobubbles of gas, including mixing gas and liquid, after mixing gas and liquid in a gas-liquid mixture, the pressure is maintained above the saturation pressure of the liquid with gas (P). The pressure in the gas-liquid mixture is maintained at 1.1-2.0 P. The ratio of the volumes of gas and liquid is determined from Henry's law at the liquid's saturation pressure with gas. The ratio of the volumes of gas and liquid is determined by the solubility curve of the gas in the liquid at the pressure of saturation of the liquid with gas. Anionic, cationic or non-ionic surfactants are additionally introduced into the gas-liquid mixture.
