method to simulate multiphase / multiple fractional component flow through porous media

摘要

method for simulating multistage flow / multiple fractional components through porous media a method for calculating or estimating multistage flow in multiple fractional components through porous media employing a 3d digital representation of a porous medium and a fluid dynamics method The computational method for calculating vectors of flow rates, pressures, saturations, internal velocity and other flow parameters is described. The method utilizes a single method of introducing non-wetting and wetting fluids into the pores on the inlet face of the digital representation 30 of a porous medium and a new process control application to achieve near steady state flow at low inlet concentrations. of non-wetting fluid. In addition, the method of the present invention reduces the time required to simulate to complete dynamic fluid calculations. values resulting from non-wetting fluid flow, wetting fluid, saturation, and other parameters are used to generate plots of drainage curves and relative permeability absorption. computer systems and programs for performing the method are also provided.
