SAND CARRIER FOR HYDRAULIC FRACTURING OF FORMATION

FIELD: oil production industry, particularly for obtaining oil, gas, water, soluble or meltable materials or slurry of minerals from wells. ^ SUBSTANCE: liquid sand carrier comprises liquid hydrocarbon, cation-active surfactant, namely product of lanolin production obtained by wool fat processing, and aqueous phase. Cation-active surfactant is emulsifier, aqueous phase is aqueous solution of calcium chloride with 1010-1020 kg/m3 density. The components are taken in the following amounts (% by weight): liquid hydrocarbon - 20-25, emulsifier - 0.5-1.5, remainder - aqueous solution of calcium chloride. Liquid sand carrier comprises gas condensate or diesel fuel or oil used as the liquid hydrocarbon. ^ EFFECT: increased carrying capacity due to increased viscosity and stability thereof and, as a result, reduced consumption sand carrier, volumetric injection rate and reduced range of necessary technical means used for hydraulic fraction performing, increased productive bed permeability recovery factor due to prevention of bottomhole formation zone contamination. ^ 2 cl, 9 ex, 2 tbl
