Abstract: In order to solve the problem of artificial interference required in the process of randomly-establishing models of the reservoirs so as to realize computerization of the whole procedure from models to simulation in such a process,this paper suggested that computers are to be used to match automatically the entire procedure of variation function. The method can be used to calculate automatically experimental variation functions in eight directions by using computers, match the theoretical variation function model in all directions and establish the unified model, providing parameters for reservoir model establishment. This method has successfully solved the problem of artificial interference in reservoir model establishment, hence improving the degree of automation in establishing reservoir models.
