DISCRETIZATION SCHEME FOR SIMULATING PROPPANT TRANSPORT IN DYNAMIC FRACTURE NETWORKS |
摘要 |
In accordance with embodiments of the present disclosure, a discretization technique may be used to solve for fluid and proppant flow through a fracture within a dynamic fracture network. The discretization technique may involve performing a spatial discretization of non-linear coupled equations by integrating the equations over staggered finite control volumes. For example, the spatial discretization may involve integrating a continuity equation representing fluid flowing through the fracture over a first control volume along the length of the fracture, integrating a momentum equation representing the fluid flowing through the fracture over a second control volume that is staggered with respect to the first control volume, and integrating a proppant equation representative of the proppant flowing with the fluid through the fracture over the first control volume. The discretized equations may be used to determine a linear system of equations to simulate proppant flow through the dynamic fracture network. |
