▎ 摘　　要

NOVELTY - The method involves mixing surface-activated graphene and industrial flue gas in underground oil and gas reservoirs to form graphene nitrogen foam and graphene super-carbon foam. An underground reservoir (4) is located at the lower end of the injection well, and pore crack space is used to inject active graphene and industrial flue gas to form a graphene nitrogen foam layer (5) and a graphene super-carbon foam layer (6). USE - Method for controlling surface-activated graphene and industrial flue gas by foaming water for driving oil and gas in high water-containing oil well, high water-containing gas well, water injection well, steam injection well and gas injection well (claimed). ADVANTAGE - The superactive graphene and industrial flue gas foam huff and puff are injected to increase oil production by injecting superficial graphene and industrial flue gas foam. The gas production well is injected with superficial active graphene and industrial flue gas foam huff and puff to control water and increase gas production. The water injection well is injected with surface active graphene and industrial flue gas foam to prevent channeling and control water to drive oil and gas. The surface active graphene and industrial flue gas are injected in the gas injection wells around the gas storage to prevent channeling and control water displacement. The need to set up a huge and complicated purification and separation system on the ground to separate and purify carbon dioxide separately is eliminated. The industrial flue gas is directly injected into carbon dioxide without purifying with low operating cost and high system operating efficiency. The oil-gas driving efficiency and oil-gas recovery ratio are improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a system for controlling surface-activated graphene and industrial flue gas by foaming water for driving oil and gas. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the whole structure of the system for controlling surface-activated graphene and industrial flue gas by foaming water for driving oil and gas.
