METHOD OF FORMATION HYDRAULIC FRACTURING Russian patent published in 2014 - IPC E21B43/267 C09K8/80

Abstract RU 2507389 C1

FIELD: mining.

SUBSTANCE: method includes filling formation with mixture of fracturing liquid with proppant agent. As proppant agent gas crystallohydrates are used. Filling is performed under thermobaric conditions of existence of gas crystallohydrates. After formation fracture gas crystallohydrates are decomposed with extraction of gaseous phase additional to splitting macro and micro-cracks of formation fracture. Filling of fracturing liquid mixture with proppant agent, formation fracture and crystallohydrates decomposition are performed one or several times.

EFFECT: improving formation permeability during hydraulic fracturing.

4 cl, 5 dwg
