发明名称 METHOD FOR HYDRAULIC RUPTURE OF LOW-PERMEABLE UNDERGROUND BED
摘要 FIELD: mining. ^ SUBSTANCE: method includes pumping of hydraulic rupture liquid, containing proppant particles, through well into crack developed in underground bed. According to invention, in process of pumping turbulent mode of fluid flowing is provided in crack by means of hydraulic rupture pumping with viscosity of less than 0.01 Pas with pumping speed of at least 8 m3/min. At the same time hydraulic rupture fluid contains particles of proppant, radius of which is determined by analytical expression in case when proppant particles are heavier than fluid, or by other analytical expression in case if proppant particles are lighter than fluid. ^ EFFECT: increased conductivity of crack after its closure due to prevention of transverse migration of proppant particles inside crack and reduction of their settling speed. ^ 3 cl
