FOAMED GEL-LIKE SYSTEMS FOR UNDERGROUND RESERVOIRS HYDRAULIC FRACTURING AND PROCEDURES FOR THEIR PRODUCTION AND APPLICATION

摘要

FIELD: gas and oil production.;SUBSTANCE: water composition for reservoir hydraulic fracturing contains water, ion-bound gel-like system including charged polymer, oppositely charged foaming agent and gas. The gel-like system and gas are present in amount sufficient for production of ion-bound foamed composition for hydraulic fracturing. Composition contains liquid for hydraulic fracturing including 5.5-7 gpt of the above said gel-like system and de-ionised water. The procedure for production of foamed compositions consists in production of the first composition, the second composition and in adding it to the first one at their specified ratio. The procedure for reservoir hydraulic fracturing includes production of liquid for hydraulic fracturing containing the above said gel-like system and proppant and in its pumping into the reservoir. The procedure for reservoir hydraulic fracturing includes production of liquid for hydraulic fracturing containing the above said gel-like system, its pumping into the reservoir at pressure of hydraulic fracturing and in pumping proppant after hydraulic fracture.;EFFECT: facilitating reservoir hydraulic fracturing at deficiency of hydration units.;45 cl, 1 tbl
