Abstract
Способ гидравлического разрыва продуктивного пласта, включающий создание депрессии на пласт, перекрывающий или подстилающий продуктивный пласт, которая вызывает упругую деформацию сжатия, последующее создание депрессии на продуктивный пласт, вызывающей его упругую деформацию, и нагнетание жидкости гидроразрыва после восстановления давления, отличающийся тем, что, с целью увеличения притока флюида из низкопроницаемых коллекторов повышенной прочности за счет достижения разрывных деформаций породы продуктивного пласта при пониженных значениях давления нагнетания жидкости гидроразрыва, после восстановления давления осуществляют повторное дренирование пласта, а жидкость гидроразрыва начинают нагнетать при забойном давлении, которое не менее чем на 5 МПа ниже пластового давления.The method of hydraulic fracturing of the productive formation, including the creation of a depression on the formation, overlapping or underlying the productive formation, which causes elastic compression deformation, the subsequent creation of a depression on the producing formation, causing its elastic deformation, and the injection of hydraulic fracturing fluid after pressure recovery, characterized in that the purpose of increasing the flow of fluid from low-permeability reservoirs of increased strength due to the achievement of discontinuous deformations of the reservoir rock with reduced x values of the injection pressure of the fracturing fluid, after the pressure is restored, the reservoir is re-drained, and the fracturing fluid is started to be injected at the bottomhole pressure that is not less than 5 MPa below the reservoir pressure.
