Abstract: In the area with complex seismic geology condition,the solutions of petroleum geologic problems are limites by the unique use of seismic survey If some non-seismic gcophysica survey was applicd objcetivcly,the situation would bc improved. In GY sag,bused on high aceuracy gracity data, we analysis the regional structure featurcs and pctrolcum geologic information, then delineatc thc local structurcs and cvaluatc hydrocarbon potential and scismic geology conditions. The resnlt is satisfied in geoogy,and it indicatcs thc ability and effect of jntegratcd gcophysical survey in solntion of petrolenm geologic problems.
