Methodology of selecting aerodynamic pattern of the ejector for injecting water-gas mixture into the formation

V.N. Kalinnikov, A.N. Drozdov


This article is devoted to the adaptation of the methodology for choosing the aerodynamic pattern of liquid-jet compressors (ejectors) by K.G. Donets for use as part of a pump-ejector system on an injection well.

For the conditions of a well of one of the fields in Tatarstan, the parameters for choosing an ejector were calculated according to a technique adapted by the authors; pressure and energy characteristics were constructed for each of the schemes proposed by K.G. Donets, given reasonable recommendations for choosing the optimal pattern.

    Key words:

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