Experimental studies on the effect of mixing chamber length on the characteristics of a liquid-gas ejector during the injection of exhaust gases to achieve a water-gas impact on formation

Experimental measurements were conducted to determine the effect of mixing chamber length on liquid-gas ejector performance. The tests were performed on a laboratory bench designed for physically modeling the process of creating a water-gas mixture using exhaust gases. For the first time in this study, liquid-gas ejector parameters were measured during the injection of exhaust gases from a real source. The study investigated how the ratios of displacement chamber diameters, chamber length, and working nozzle affect the liquid-gas ejector's characteristics under various operating modes. The results obtained enable optimal parameter selection of the ejector and reveal the potential for utilizing exhaust gases to produce a water-gas mixture for injection into reservoirs to enhance oil recovery.
