Abstract

The invention discloses a fracture-cavity type carbonate oil reservoir three-dimensional physical model establishing method and relates to the technical field of three-dimensional modeling methods for computer mapping. The fracture-cavity type carbonate oil reservoir three-dimensional physical model establishing method mainly comprises the following steps of selecting a three-dimensional earthquake image corresponding to a target region according to three-dimensional earthquake test data and actual production situation, utilizing a Kriging interpolation method to reconstruct a three-dimensional numerical model through a three-dimensional earthquake cross section image, compiling an engraving program to manufacture a three-dimensional physical model and applying a similarity theory to arrange a well position according to the actual situation of an oil reservoir. By means of the fracture-cavity type carbonate oil reservoir three-dimensional physical model establishing method, the fully-three-dimensional large-sized physical model consistent to an actual underground structure and morphology of the oil reservoir and capable of representing fracture-cavity type carbonate oil reservoir complicated characteristics can be obtained.

Description

technical field [0001] The invention relates to the technical field of a 3D modeling method for computer graphics, in particular to a method for establishing a three-dimensional physical model of a fracture-cavity carbonate reservoir. Background technique [0002] Whether the underground fracture-vuggy structure, connection type, and oil-water relationship can be clearly understood is one of the foundations for the efficient development of fractured-vuggy carbonate reservoirs. There are various fluid flow channels such as fractures and karst caves in fractured-cavity carbonate reservoirs, and the fractures and karst caves have large sizes, large scale changes, various shapes and random distribution. As a result, the flow state between oil and water is extremely complex, and there are various flow characteristics such as seepage flow, nonlinear seepage flow, pipe flow, surface flow, convection flow and coupled flow. The law of oil and gas production is also extremely complex...
