Abstract
1. Способ проведения гидроразрыва пласта с использованием двух жидкостей, заключается в том, что формирование трещин гидроразрыва идет путем нагнетания двух жидкостей с большей и меньшей плотностями, отличающийся тем, что одна из жидкостей имеет более высокий предел текучести.2. Способ по п.1, отличающийся тем, что жидкость с большей плотностью имеет более высокий предел текучести.3. Способ по п.1, отличающийся тем, что жидкость с меньшей плотностью имеет более высокий предел текучести.4. Способ по п.1, отличающийся тем, что закачка двух жидкостей осуществляется через одну скважину.5. Способ по п.1, отличающийся тем, что у одной жидкости предел текучести равен нулю.6. Способ по п.1, отличающийся тем, что закачивается третья жидкость, причем все жидкости имеют разные плотности, а жидкости с наименьшей и наибольшей плотностями имеют более высокий предел текучести.7. Способ по п.1, отличающийся тем, что используется более двух жидкостей, причем у жидкости с минимальной и/или максимальной плотностью предел текучести больше, чем у любой другой.1. The method of hydraulic fracturing using two fluids consists in the formation of hydraulic fractures by injecting two fluids with higher and lower densities, characterized in that one of the fluids has a higher yield strength. The method according to claim 1, characterized in that the liquid with a higher density has a higher yield strength. Method according to claim 1, characterized in that the liquid with a lower density has a higher yield strength. The method according to claim 1, characterized in that the injection of two fluids is carried out through one well. Method according to claim 1, characterized in that one liquid has zero yield strength. Method according to claim 1, characterized in that a third liquid is pumped, wherein all liquids have different densities, and the liquids with the lowest and highest densities have a higher yield strength. The method according to claim 1, characterized in that more than two liquids are used, and the liquid with the minimum and/or maximum density has a higher yield strength than any other.
