METHOD FOR SIMULATING MOVEMENT OF SEPARATE PHASES OF MULTIPHASE/MULTICOMPONENT FLOW PASSING THROUGH POROUS MEDIUM Russian patent published in 2016 - IPC G01N15/08 G01N13/00 G06F17/50 

FIELD: measurement technology.

SUBSTANCE: invention relates to a method of computing or estimating the parameters of separate phases of multi-phase/multi-component flow passing through a porous medium employing a three-dimensional digital representation of the porous medium and a computational fluid dynamics method for calculate flow rates, hydrodynamics pressures saturations, internal velocity vectors and other flow parameters. Method employs a unique method of introducing non-wetting and wetting fluids into the pores at an inlet face of a three-dimensional digital representation of a porous medium and a novel process control application to achieve quasi-steady state flow at low inlet concentrations of non-wetting fluid. In addition, the method of the present invention reduces time required to simulate to complete the fluid hydrodynamic calculations. Resulting values of flow of non-wetting fluid, wetting fluid, saturation, and other parameters are used to generate plots of relative permeability imbibition and drainage curves. Computerized systems and programs for performing the method are also provided.

EFFECT: disclosed is a method of computing or estimating the parameters of separate phases of multi-phase/multi-component flow.
