Claims12
A method for increasing production and injection of a carbonate reservoir coupled with flue gas desulfurization and denitrification, characterized in that:
- a desulfurizing and denitrating agent is mixed uniformly with H2O2 solution to prepare a solution, and the solution is sprayed into a flue gas in an opposite direction of flue gas flow to obtain a waste liquor;
- or O3 is mixed into the flue gas in the opposite direction of flue gas flow, and simultaneously the desulfurizing and denitrating agent is sprayed into the flue gas to obtain the waste liquor;
- when the pH of the solution system reaches 6 to 6.5, the waste liquor is collected as an acid liquor and injected into a reservoir to increase production and injection thereof;
- the desulfurizing and denitrating agent comprises Tetrahydroxyethyl Ethylenediamine (THEED) or 2,2′-Bipyridine (bipy) solution with a mass fraction of 0.010% to 0.025%.
