PROPPANT AND PRODUCTION METHOD THEREOF Russian patent published in 2012 - IPC C09K8/80 C04B35/653 

FIELD: chemistry.

SUBSTANCE: invention relates to production of proppants used in oil and gas extraction using a penetrating fluid method. In the method of producing a proppant used when extracting oil and gas using a penetrating fluid method involves preparation of the starting mineral material, melting the material to obtain granules in a gas-discharge low-temperature plasma reactor, cooling the granules and screening said granules into commercial-grade fractions, the surface of the granules is cooled at a rate of more than 1.0-10⁶ °C/s. The proppant, which is used when extracting oil and gas using a penetrating fluid method, obtained using said method in form of granules with diameter 100-2000 mcm and pycnometric density 1.0-3.5 g/cm³, from mineral material consisting of a core and cladding, where the cladding has an amorphous structure. The invention is developed in the dependent claims of the formula.

EFFECT: high efficiency of producing proppants, high strength and conductivity of packaging of proppants in the hydraulic fracture crack.
