چکیده مقاله:

A bubble train model is proposed to describe coupled gas condensate flow in porous media. The total pressure drop of the flow is determined based on the dynamic wetting properties of the system, i.e. bubble configuration and residual condensate film thickness. The role of disjoining pressure in dynamic wetting was included in this model to account for the micrometer size effect of the pores in low permeability reservoirs. The single-pore flow model developed in this way qualitatively predicts the effect of interfacial tension and the absolute permeability of the reservoir on gas condensate relative permeability. Furthermore, the flow model is used in a bundle of capillary tubes model to predict pressure drop and relative permeability in gas condensate flow through a low permeability core sample. Despite the simplicity of the upscaling method, excellent agreement between the model and experimental data is achieved.
