Potential analysis for petroleum exploration in the area of south fault-terrace belts in Gaoyou Depression

The exploration in south fault-terrace belts of Gaoyou Depression is of low benefit owing to its fractured structure and complex oil-forming condition. We think that the area has great potential for petroleum exploration through analyzing the conditions of structure, oil source, secondary migration of hydrocarbon, reservoir, preservation and the quality of seismic data. And we can gain big breakthrough in petroleum exploration as long as we strengthen our recognition ability in structure and analyze the law of reservoir generation.
