Method for creating facies probability cubes based upon geologic interpretation

摘要

Disclose a kind of method for creating an appearance probability cube. A S- grid comprising appearance is created first. Grid includes the layer of unit and the column of unit. By source, such as well data, the vertical geologic section and chart for describing the concept of the ratio of the appearance found in each layer obtains the vertical aspect ratio data of layer for unit. Areal depocenter map is created, and has determined boundary line to create the maximum deposition region for being wherein likely to occur respective appearance. It is desirable that being used for the boundary of the maximum deposition region of each appearance sequentially and being independently defined. By filtering maximum deposition region, horizontal or figure aspect ratio data are generated preferably for the column of unit, so that the ratio of each appearance is located at range from a maximum value a to minimum value. Then vertical and horizontal aspect ratio data are integrated to one appearance probability cube of creation, and wherein unit is endowed the probability of the appearance for appearance.
