FIELD: oil and gas production. ^ SUBSTANCE: procedure is performed like follows: (a) in pumped fluid there is facilitated contents of synthetic gas from 0.1 to 20 mol % in terms of dry gas, also, pumped fluid is produced by means of partial oxidation of carbon containing source of synthetic gas with air; (b) pressurised fluid is pumped into underground section to build specified pressure; (c) fluid containing hydrocarbons is extracted from underground section. The system for production of pumped fluid containing from 0.1 to 20 mol % of synthetic gas designed for pressurising into the underground section contains at least: the first reactor-gasifier consisting of an inlet orifice for flow containing oxygen, of an inlet orifice for hydrocarbon flow and of an outlet orifice downstream the first reactor-gasifier for flow containing synthetic gas produced in the first reactor-gasifier. Further, the system has the second reactor-gasifier consisting of an inlet orifice for the second flow containing oxygen, of an inlet orifice connected with the outlet orifice of the first reactor-gasifier and of an outlet orifice, positioned downstream the second reactor-gasifier, for pumped fluid produced in the second reactor-gasifier. ^ EFFECT: raised efficiency of inventions due to reduced contents of oxygen in composition of pumped fluid designed for improved extraction of hydrocarbons. ^ 24 cl, 3 dwg, 1 tbl |
