Research and Application of Three-Dimensional and Three-Phase Nonlinear Flow Numerical Simulator in Ultra-low Permeability Reservoir

A nonlinear flow reservoir mathematical model is established, and the numerical stimulation program is compiled based on black-oil model, whose purpose is to simulate the fluid flow in ultra-low permeability reservoir. Actual field data is used to make a pilot calculation, and the comparative stimulating results analysis under different nonlinear flow curves and Darcy flow is provided, which has verified the ultra-low permeability reservoir developing characteristics. The nonlinear flow numerical simulation technique could anticipate the dynamic fluid flow characteristics in ultra-low permeability reservoir more exactly.
