Modelling of gas condensate relative permeability and its impact on prediction of reservoir performance

摘要

Experimental studies conducted using glass-micro-model and steady-state relative permeability measurements on cores of different lithology have shown that hte relative permeability of gas-condensate fluid systems is a function of interfacial tension (IFT) and flow rate. Experimental tests have demonstrated that, specifically the gas phase relative permeability, could be improved by a reduction in IFT and an increase in the flow rate. Contrary to the widely held view that an increase in the fluid flow rate will introduce inertial effects which reduce the ability of the gas phase to flow, it was demonstrated experimentally tha tincreasing the flow velocity to moderate values produce the opposite effect.
