The process of steam-thermal treatment has been carried out for highly-viscous oil from Ashalchinskoye accumulation with the “steam-oil” ratio changing from 1.1:1 to 1.4:1. The extraction process has been carried out at temperature T = 85°C and pressures from 4.5 to 8 MPa. Water absorption of carbonate rock has decreased to 0.34% as a result of SCF-impregnation process.展开更多
