Abstract:Jiyang Depression is a typical continental faulted basin in eastern China. It has experienced 60 years of exploration and development and entered a fine exploration stage of complex subtle reservoirs. Given the high degree of exploration and resource discovery,small and hidden exploration targets,and other grave situations,it is necessary to deepen oil and gas exploration and realize large-scale storage increase and efficient exploration. After the systematical analysis of the existing exploration state and key problems,it is considered that the exploration degree in the Upper Submember and its upper strata of the Fourth Member of Shahejie Formation in Jiyang Depression is high,which is a mature field. The exploration degree in the Lower Submember and its lower strata of the Fourth Member of Shahejie Formation is low,which belongs to the “three-new”field. In addition,shale oil and gas resources have great potential,representing an alternative exploration field. In light of different exploration fields,corresponding exploration ideas are put forward,namely fine exploration in mature fields for stable reservoir increase,risk exploration and preliminary prospecting in the“three-new”fields for large-scale discovery,and in-source exploration of shale oil and gas fields for a long-term plan.
