FIELD: oil and gas production. ^ SUBSTANCE: granules of material used to reduce proppant carry-away from hydraulic rupture crack are made of polymer material, with the property to increase its hardness in well under temperature effect or by means of granule material interaction with oil, gas-condensate or water in process of oil products extraction, besides specified polymer material contains filler and additionally contains plasticiser and ageing inhibitor, with the following ratio of components, wt %: filler 0.01-40; plasticiser 0.01-60; ageing inhibitor 0.01-20; polymer material - the rest. Material particle size makes from 4 mesh to 60 mesh. ^ EFFECT: development of new material in the form of particles with controlled varying hardness in crack conditions. ^ 1 tbl, 1 ex |
