COMPOSITION OF FLUID FOR INTENSIFICATION OF OIL AND GAS PRODUCTION Russian patent published in 2018 - IPC C09K8/86 C09K8/68 C09K8/52 E21B43/267 

FIELD: mining.

SUBSTANCE: present invention relates to a carrier fluid for hydraulic fracturing of a formation in an underground reservoir. Carrier fluid for hydraulic fracturing of a formation for hydraulic fracturing of an underground reservoir containing at least one linear or branched hydrofluorocarbon ether compound, having a boiling point at a pressure of 1 atmosphere (101,325 Pa) from 0 to 90 °C. Fracturing fluid comprising at least one above-mentioned fracturing carrier fluid and proppants. Method of hydraulic fracturing of a formation of an underground reservoir using the above fracturing fluid, comprising at least the following steps: a) providing the said carrier fluid for fracturing the formation with the possibility of compression and / or cooling, so that the carrier fluid for fracturing is in the form of a liquid, preparing the fracturing fluid by mixing the liquid carrier fluid for fracturing the formation from step a) with proppants in the vessel to produce a liquid fracturing fluid, and c) injecting the said fracturing fluid from step b) into an underground reservoir at a pressure sufficient to open one or more faults therein. Invention is developed in dependent items of the formula.

EFFECT: higher efficiency of processing.
