The pattern of the subtle traps, in which oil and gas accumulated, in the buried-hill faulted zone in the Jiyang sag is very complicated, and very hard to prospect. The paper analyses the main difficulties in exploring the complicated buried-hill faulted zone of the area from a point of geology.The typical pattern of the buried-hill zone in the Jiyang sag is studied using the forward modeling.Target-orient layout design and full 3-D seismic technology, which are useful for oil and gas exploration on the zone, are put forward. Taking the exploration for oil and gas traps on the zone as an example, certain technologies and the effect of their applications about the design for target acquisition,acquisition on a wide-azimuth, point sources and point receivers are discussed.
