Oil sands,as an important supplement to petroleum,occupy a high position in the international energy supply.Researches show that the mineralization is characterized by the"Five in One"process of generation,migration,storage,destruction and preservation,which throughout the entire mineralization process,and the storage,destruction and preservation are more important for the oil sands mineralization.Analysis suggests that the development of primitive oil reservoirs is the material basis for the formation of oil sands,and the role of storage and preservation is the key control factor for the scale and oil content of oil sands.Conventional oil and gas in the same basin and unconventional oil and gas such as oil sands and shale oil and gas have the same origin.Therefore,comprehensive oil and gas exploration should be carried out based on the concept of oil and gas systems,with a focus on searching for oil sand deposits in areas where faults crisscross,unconformities,and sand bodies in primitive oil reservoirs are developed.The study of the process of oil sand mineralization has important implications and reference significance for exploring the conventional and unconventional oil and gas in the deep and edge of oil sand deposits.
