FEED FOR MANUFACTURING OF LIGHT-PROOF SILICON PROPPANT AND PROPPANT Russian patent published in 2018 - IPC C09K8/80 C04B35/14 E21B43/267 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas production industry, namely to the technology of manufacturing siliceous lightweight ceramic proppants intended for use as proppants in the production of oil or gas by hydraulic fracturing of the formation - fracturing. Feed for the manufacture of lightweight silica-containing proppant, comprising a silica-containing component, a magnesium-containing component, further comprises cement and / or cement clinker with the following ratio of components, mass%: magnesium-containing component 0.1-10, cement and / or cement clinker 0.1-10, silica-containing component - the balance. Lightweight siliceous proppant is characterized by the fact that it is obtained from this charge. Invention is developed in subclaims.

EFFECT: technical result is a reduction in the breakdown of siliceous proppant with a bulk density of less than 1,4 g/cm³ at a load of up to 10 thousand psi.
