COMPOSITION TO UP BED PRODUCTION RATE (VERSIONS) Russian patent published in 2016 - IPC C09K8/584 

FIELD: oil and gas industry.

SUBSTANCE: composition intended to up the bed production rate consisting of surfactant, sodium tetraborate (sodium borate) and water contains additionally commercial or distilled glycerine with the following ratio of components by wt %: surfactant 1.0-4.0, sodium tetraborate (sodium borate) 2.0-30.0, glycerine 10.0-90.0, water - the remaining share. According to another version composition intended to up the bed production rate consisting of surfactant, sodium tetraborate (sodium borate) and water contains additionally commercial or distilled glycerine and carbamide with the following ratio of components by wt %: surfactant 1.0-4.0, sodium tetraborate (sodium borate) 2.0-30.0, glycerine 10.0-80.0, carbamide 2.0-20.0, water - the remaining share. The invention has been developed in the dependent claims.

EFFECT: improved coverage ratio for beds in the impact zone, residual oil washing both from high- and low-permeable bed zones, improved viscosity of the working fluid and alignment of mobility for displaced agent and displacing agent, compatibility with mineralised brine water.
