It is the synthetical, general, macro and visual Characteristics of remotely sensed image that makes remote sensing technigue a successful way to find oil-gas fields. on the basis of study of the relations between linearment, ring feature, geological structure and the distribution of oil-gas fields, three oilgas prediction models of remote sensing are established in the paper. Using mainly the three models with other geological models, synthetical prediction of oil-gas is made in Jiyang Depression on microcomputer, and some oil-gas prospect ranges are pointed out.The research shows that the method presented here is simple, convient and may lower the cost greatly in oil-gas exploration.
