Method for predicting dynamic parameters of fluids in a subterranean reservoir

摘要

A method for determining the location of the accumulation fluids in a subterranean formation. The method includes the steps of determining a first velocity vector "Vx" for migration of fluid in a region of interest in the subterranean formation. The first velocity vector includes attributes of speed and direction of flow of fluid in a first direction in the region of interest. The method further includes determining a second velocity vector "Vy" for migration of fluid in the region of interest. The second velocity vector includes attributes of speed and direction of flow of fluid in a second direction in the region of interest. The velocity vectors are then extrapolated to identify the fluid accumulation location. The first and second velocity vectors are primarily functions of supplementary pressure "dP" in the region of interest, the permeability "c" of the region of interest, and the viscosity "u" of the fluid in the region of interest. The supplementary pressure can be determined by identifying pressure gradients within the region, the region being characterized by a seismic image of a stacked time section representing horizons within the region. The permeability of the media within the region, and the viscosity of the fluid within the region, can either be determined mathematically or from geological data.
