Multiphase flow in a wellbore and connected hydraulic fracture

摘要

One or more computer-readable media include computer-executable instructions to instruct a computing system to iteratively solve a system of equations that model a wellbore and fracture network in a reservoir where the system of equations includes equations for multiphase flow in a porous medium, equations for multiphase flow between a fracture and a wellbore, and equations for multiphase flow between a formation of a reservoir and a fracture. Various other apparatuses, systems, methods, etc., are also disclosed.

1. A method comprising:
providing a reservoir model of a reservoir wherein the reservoir model comprises a three-dimensional grid that defines grid cells in a reservoir model space; providing a well model of a well and a hydraulic fracture that intersects the well wherein the well model comprises segments within the reservoir model space that comprise fracture connections to a number of the grid cells of the reservoir model without a demand for finer grid cells of the reservoir model and wherein the well model comprises an associated system of equations that accounts for multiphase flow between the hydraulic fracture and the well and between the reservoir and the hydraulic fracture based at least in part on pressures of the reservoir model; and solving, using a computing device, at least the system of equations for the well model to generate a solution.
