The conditions of the actual tight sandstone reservoirs were applied as experimental conditions to implement indoor physical CO 2 and N 2 flooding simulation experiments. To achieve optimal experimental conditions, CO 2 and N 2...

... of the proposed system is evaluated during chelating agent injection. Several dual coreflooding experiments were performed to examine the performance of this diverting system at 130°C. Experimental Studies Materials The chelating agent used for acidizing was glutamic acid diacetic acid (GLDA...
