Abstract: On the basis of geoanchored method, the prediction of the numbers and resource extent of undiscovered oil and gas fields in the north of Songliao basin are made and correlated with those by fractal method. The result shows that the numbers and accumulations of undiscovered oil and gas fields predicted with geoanchored method is apparent less than those predicted with fractal method,but geoanchored method is still a newly reliable way to predict the numbers and resource extent of the oil and gas fields, especially has the good application result in highly explored basins and zones. The prerequisite to predict the numbers and resource extent of the oil and gas fields with geoanchored method is to make a classification of reservoir-formed system; the system is only suitable in geological definition, the geoanchored method is of function for prediction. Because the method emphasizes the discovered relative sequence of a reservoir in the process of predicting the numbers and accumulations of the oil and gas fields,compared with another resource assessment methods, the predicted result with geoanchored method should be minimum.

Key words: prediction, resource extent, oil and gas field, geoanchored method
