Abstract: The results of calculations of immiscible fluid flow to an operating well are compared for various formation parameters and states of the wellbore zone. Steady-state and unsteady filtration regimes are considered. The calculations show that acidizing of the wellbore zone increases the well flow rate.

Keywords: two-phase filtration, acidizing, numerical modeling.
