Logging technology, 2000, 2004 (1): 47 ~ S43 heterogeneous reservoir core and oil test data, the logging geologic data of more than 170 wells in the early and late S43 and S43 oilfields of the Shahejie Formation in the area were processed by using gray system theory and neural network technology. The reserves parameters such as the oil-bearing area, the effective thickness of the oil layer, the porosity, the original oil and the remaining oil saturation were obtained. According to the calculation unit of the small reservoir, the reserves parameters of each small reservoir were extracted and aggregated, Model networked parameters, the original oil and remaining oil reserves of 16 small reservoirs in S43 and S43 oilfields were calculated by grid integral method. The effects of S43 5, S43 3, S43 4, S43 2, S43 6, S43 8, S43 7 and S43 1, S43 2 small reservoirs of the remaining oil distribution, pointed out that the main three sub-reservoir heterogeneity and the main target of tapping potential adjustment
