According to the geologic and development characteristics of Gudao and Gudong oil fields in the east ofZhanhua sag, Jiyang depression, some new theories, methods and technologies of predicting thedistribution of the remaining oil have been put forward which include dynamic state combined with staticstate, multiple disciplines synthesized, and predicting it finely, quantitatively and comprehensively fromgeology, logging, reservoir engineering, and production dynamic state datum etc., limited by geologicconditions. Very good applying achievements have been obtained.
