Investigation of the ejector`s characteristics for the system of injection of water-gas mixtures into the reservoir

Abstract

Implementation of SWAG injection by means of injection of a water-gas mixture is a promising method for increasing oil recovery. The use of associated petroleum gas as gas components in the water-gas mixture allows a multiple reduction in the amount of irrationally consumed gas and a reduction in the carbon footprint. This article uses the technology of multi-stage ejector reproduction to obtain and pump a water-gas mixture in plastic. The right choice of equipment allows you to operate the system with maximum efficiency. The article presents a schematic diagram of the SWAG installation. The effect of the working pressure on the efficiency of the ejector has been studied. Dependences of pressure-energy characteristics are obtained. Keywords: water-gas mixture; pumping-ejector system; SWAG technology; liquid-gas ejector; pressure-energy characteristics of ejectors.
