FORMATION HYDRAULIC FRACTURING METHOD

摘要

FIELD: oil and gas industry. ^ SUBSTANCE: method involves pre-injection of material to the formation and performance of formation hydraulic fracturing. According to the invention, material pre-injection is performed until maximum injection pressure is set. When the injection pressure is achieved, formation hydraulic fracturing operations are started. As pre-injected material there used is invert oil emulsion containing stock oil in quantity of 0.35-0.45 volume parts, emulsifier in quantity of 0.05-0.06 volume parts, formation Devonian water with density of 1170-1180 kg/m3 in quantity of 0.5-0.6 volume parts. ^ EFFECT: improvement of hydraulic fracturing operation. ^ 1 ex
