Pressure Distribution of Heavy Oil Seepage at Different Particle Shape Coefficient and Kinematic Viscosity

Abstract

Pressure distribution in heavy oil reservoir was numerical simulated by calculating varying-coefficients Darcy’s equation with boundary element method (BEM) in this paper. Permeability coefficients of Darcy’s equation at different parameters were numerical simulated firstly. Then the pressure contours of nine-spot pattern were given. The simulated results show that the particle shape coefficient and kinematic viscosity have major impact on permeability coefficient. In addition, the influence of permeability coefficient on seepage pressure is obvious. Numerical simulated results can provide quantitative theoretical basis for the well deployment and production estimation in the heavy oil exploitation. The reasonable numerical results indicate that the BEM is effective in dealing with heavy oil seepage problems.
