BASICS OF MATHEMATICAL MODELING OF GAS LIFT PROCESS IN THE WELL-RESERVOIR SYSTEM

Abstract

The paper is devoted to the problem of mathematical modeling of the gas-lift wells in the wellreservoir system. Results of field experiments carried out in the well of the offshore field "Neft dashlari" (Azerbaijan) are represented. Has been formulated the basic principles of modeling of the gaslift wells. An approach is proposed to account for the real processes at the zone of the gas-liquid mixture for modeling the considered process. This takes into account the dynamic processes occurring in
the wellbore and in the reservoir, real properties of fluids and porous medium during filtration.
