Image constructing method for e.g. hydrocarbon deposit, involves calculating law of probability of categorical physical property, and determining value of categorical property by performing random selection in law for constructing image

摘要

The method involves constructing learning images representing a geometrical structure of categorical physical property and distribution of auxiliary physical property e.g. seismic amplitude, respectively. A histogram of categorical property`s values and a histogram of auxiliary property`s values are determined. A law of probability of the categorical property is calculated, from the histograms and auxiliary property distribution data, for each pixel of an image to be constructed. A categorical property`s value is determined by performing random selection in the law to construct an image.
