Abstract: A method for increasing production and injection of a reservoir coupled with flue gas desulfurization and denitrification includes a flue gas desulfurization and denitrification process and a reservoir acid liquor acidizing process, where the flue gas desulfurization and denitrification process is mixing a desulfurizing and denitrating agent with H2O2 solution uniformly to prepare a solution, and spraying it into a flue gas in an opposite direction of flue gas flow, or mixing O3 into a flue gas in an opposite direction of flue gas flow, and simultaneously spraying a desulfurizing and denitrating agent solution. When the pH of the solution system reaches 6 to 6.5, the reacted waste liquor is collected as an acid liquor. The process can control atmospheric pollution, improve the economic efficiency of flue gas treatment, and can prepare acid liquor cheaply.
