FIELD: gas and oil production.
SUBSTANCE: procedure for preparing propping agent with coating consists in application of coating on surface of granule. Coating consists of binding and fibre, part of which projects beyond borders of a binding layer. Ratio between length of each fibre and diametre of granule is from 0.06 to 0.44. Additionally, there is carried out treatment with silicon-organic or fluoric-carbon oil-wetting agent at amount from 0.5 to 10% of fibre weight. Propping agent is prepared by the above described procedure. The invention is developed in dependent points of formula.
EFFECT: reduced water-cut of hydrocarbon raw stock at operation of well.
