Abstract: As a typical representative of continental fault basins in China, the Jiyang Depression has experienced 3 exploration stages; from structural exploration of large anticlines, through complex oil and gas accumulation belts, to subtle oil and gas reservoirs. At present, exploration objectives in the Jiyang depression are more complex and subtle, which requires a more elaborate degree of exploration research, deployment, and management. By strengthening the dynamic evaluation of the remaining resource potential in the depression, continuously deepening understandings of geological laws, and research and application of exploration supporting technologies, fine evaluation of exploration targets has been carried out in the Shengli Oilfield to achieve continuous and stable increase of reserves in the Jiyang depression. This paper systematically summarizes exploration practice in the Jiyang depression and presents the ‘five fine work and two innovations’ exploration method, which is of great theoretical and practical significance for the exploration and stable development of continental fault basins in eastern China which have experienced a high degree of exploration.
