Method for visualization of fluid filtration in heterogeneous porous medium

摘要

A method and system for visualization of a direction of a fluid flow in heterogeneous porous medium in hydrocarbon reservoirs based on the streamlines. The method allows for constructing the detailed and accurate model of a direction and a volume of the fluids being transferred between the wells and can be used for analysis of waterflooding and hydrodynamic connectivity between the wells used in oil and gas reservoirs with a large number of wells. The visualization method can be used both for analysis of instantaneous fluid flows at the current calculation step of hydrodynamic simulator and for analysis of fluid flows accumulated over several calculation steps.

1. A computer-implemented method of visualization of fluid flow direction in heterogeneous porous medium in hydrocarbon reservoirs based on streamlines, the method comprising:
determining streamlines using particles tracing on a basis of a three-dimensional pressure map and a reservoir porosity and a permeability properties; determining pairs of injection and production wells having fluid flow between them, on a basis of streamlines; building a graph of fluid flows between the injection and production wells, having the injection and the production wells serve as graph vertices connected by an edge; and visualizing the graph edges in a form of curves constructed by an interpolation of points obtained from the streamlines.
