Geological Analogy Expert System of Oil-Generating Depressions

摘要

The geologic analogy expert system of oil-generating depressions(GAESOD)constructed on IBM386 by using GCLISP language is a tool-type expert system for geologic analogy.GAESOD consists ofeight parts:(1)illustrating module of system;(2)general controlling module;(3)knowledge base;(4)rea-soning module;(5 )data base;(6)explanation module;(7)gaining and managing module of knowledge;(8)managing module of data base.There are 36 known models of oil—generating depressions of the eastern partand me continental shelf of China in the knowledge base.Three values,such as resemblance coefficient,cer-tainty factor and fine-poor coefficient,will be acquired if this system is applied to any two oil-generatingdepressions.Finally,GAESOD are applied to the analysis of some data from Xichang depression,Hepubasin and the conclusions from this system are consistent with the results from geologic experts.
