FIELD: oil and gas industry.
SUBSTANCE: composition of formation fracture fluid includes base fluid consisting of a mixture of paraffins, olefins, oxygenates and optionally terpene or a mixture of terpenes; besides, base fluid has viscosity of 1.6 to 3.3 cSt at 40°C, ignition temperature of higher than 60°C and solidification temperature of lower than -6°C; in addition, the composition contains a complex of additives to the formation fracture fluid. Besides, an underground formation fracturing method using the above composition and a method for its preparation are described.
EFFECT: obtaining nontoxic environmentally safe and biodecomposed base fluids.
