Application of the Boundary Integral Method to Immiscible Displacement Problems

摘要: This paper presents an application of the boundary integral method (BIM) to fluid displacement problems demonstrate its usefulness in reservoir simulation. A for solving two-dimensional (2D), piston-like incompressible fluids with good accuracy has been developed. Several typical example repeated five-spot patterns were solved various mobility ratios. The solutions compared analytical accuracy. Singularity programming was found be a major advantage handling flow vicinity wells. BIM excellent way solve immiscible problems. Unlike analytic methods, it can accommodate complex shapes and does not suffer from numerical dispersion at front.
