Abstract

This article is devoted to the development and calculation of a pump-ejector system for the implementation of SWAG on the reservoir in the conditions of the N. field.

The practical significance of water-gas stimulation by injecting into the formation a fine-dispersed water-gas mixture consisting of water, nitrogen and a foaming surfactant is considered.

For the N field, a diagram of a pump-ejector system was developed and its parameters were calculated, at which it is possible to implement water-gas treatment with high efficiency. The given schematic diagram of the pump-ejector system takes into account the need for injection of nitrogen and surfactants. The pressure and energy characteristics of the ejector are calculated, the calculation methods are indicated. The choice of the booster pump is substantiated.

Key words:

pump-ejector system; water-gas mixture; associated petroleum gas; injection of a water-gas mixture using nitrogen
