Casing logging technology has unique applications in residual oil saturation evaluation,flooding degree evaluation,leakage oil and gas reservoir identification,etc.,and the Tahe Oilfield is selected to identify thin interbeds by casing logging technology.The evaluation of the flooding degree of Daqing Oilfield and the application of casing logging technology were discussed.The results show that the casing technology can effectively find thin or poor oil and gas reservoirs,and qualitatively reflect the flooding degree of oil and gas layers,which is of great significance for oil and gas production.
