Method of measuring the rates of water-gas mixtures injection wells during the exploitation of oil fields

Abstract

A method and device are proposed for implementing SWAG injection by pumping a water-gas mixture. The proposed technical solution will allow to regulate and measure the flow rate of the mixture injected into each injection well. At the same time, the technology contributes to an increase in oil recovery. The device for implementing the technology makes it possible to withdraw associated gas from the annulus of production wells, which helps to reduce pressure below critical values and prevent disruptions in the supply of well products to the pumps. The device contains diaphragms - measuring devices for controlling the flow of water-gas mixtures, which are injected into selected injection wells by means of booster pumps. Keywords: water-gas mixture; pumping-ejector system; SWAG technology; liquid-gas ejector; pressure-energy haracteristics of ejectors; diaphragm.
