FIELD: oil and gas industry.
SUBSTANCE: in the manufacturing method of light-weight siliceous proppant, which involves drying and grinding of components of initial charge containing the silica source material in the form of quartz-feldspar sand, its granulation, calcination of obtained granules and screening, Portland cement is additionally introduced into the charge with the following component ratio, wt %: quartz-feldspar sand - 85-99, Portland cement - 1-15. Siliceous proppant is characterised by the fact that it has been obtained with the above method.
EFFECT: reduced proppant degradability at high pressure.
