There are advantageous conditions for shale oil and gas accumulation in Jiyang depression, but it should be studied in depth because of its poor exploration effect. On the basis of shale oil classification, differences between shale oils were analyzed. According to shale oil storage space and its hosting rock type, 2 shale oil types were divided: mudstone-shale type, interlayer type. Mudstoneshale type includes matrix type and fractured type. Interlayer type includes sandstone interlayer type and carbonate rock interlayer type. Shale oils are defined as fractured type when fracture development coefficient is more than 0.2. Shale oils are defined as matrix type when fracture development coefficient is less than 0.2. Differences exist in many aspects including shale oil distribution, fluid types, physical properties, storage spaces, occurrence states and deliverability of different type shale oils. Fractured type shale oils and interlayer type shale oils occur in larger storage space with better physical properties and free occurrence state. Therefore, the deliverability of fracture type and interlayer type shale oils are higher than that of the matrix type shale oils. The storage spaces for interlayer type shale oils with high gas-oil ratio are less than those for fractured type shale oils. Therefore, the deliverability of interlayer type shale oils is lower than that of fracture type shale oils.
