METHODS AND SYSTEMS FOR SIMULATING MULTIPHASE FLOW THROUGH POROUS MEDIA

摘要

The present disclosure provides for generating multiphase flow properties of porous media based on one or more input parameters. For instance, the multiphase flow properties may be a capillary pressure-saturation relationship for the porous media. The one or more input parameters include an interfacial tension along an interface between a wetting fluid and a non-wetting fluid, a contact angle between the interface and a pore wall of the porous media, and a pore throat size. The pore throat size is based on subparameters including a saturation of the wetting fluid, a saturation of the non-wetting fluid, a porosity of the porous media, and an orientation angle between a representative pore body size and a representative pore throat size.
