FIELD: oil and gas industry.
SUBSTANCE: in manufacturing method of light-weight siliceous proppant, which involves drying and grinding of components of initial charge, its granulation, calcination of obtained granules and screening, to siliceous charge containing the material - silicon dioxide source in the form of quartz-feldspar sand and/or quartzite there additionally added is material - magnesium oxide source with particle size of 5 mcm and less at the following component ratio (in terms of calcined substance), wt %: SiO2 88-94; MgO - 0.3-9, and natural impurities are the rest. Proppant is characterised by the fact that it has been obtained with the above method. Invention has been developed in dependent claims.
EFFECT: reducing absolute density of proppant at maintaining the strength of proppant and allowable values of breaking characteristics of proppant.
