COMPOSITION OF CHEMICALS FOR CHEMICAL CONVERSION OF BITUMINOUS OIL DURING STEAM INJECTION Russian patent published in 2023 - IPC B01J23/04 B01D11/04 B82Y40/00 

FIELD: oil and gas.

SUBSTANCE: composition of reagents for the chemical conversion of heavy oil during steam injection is disclosed. The composition includes a hydroreacting substance with a nanoscale content of alkali metals from the Li, Na, K group, a hydrogen-donor solvent nefras C4-155/205, and a water-alcohol mixture. As alcohol used aliphatic alcohol with the general formula C_nH_(2n+1)OH, where n=1÷4. In this case, the ratio of alcohol and water is (1÷5):1. The composition of the reagents is formed at the following ratio: hydroreactive substance based on one of the alkali metals : nefras C4-155/205 : water-alcohol mixture = 1-5 wt.% : 55-89 wt.% 10-30 wt.%

EFFECT: composition of chemicals for chemical conversion of heavy oil during steam injection, which makes it possible to provide more intensive heating of the reservoirs and save energy due to the exothermic reaction of alkali metals with water and the decomposition of asphalt-resin-paraffin deposits under the influence of the resulting alkali.
