The main sedimentary facies type of J1s2 is delta front subfacies in northern Mosuowan area of Junggar Basin,where developed three types of interbeds:muddy,calcareous and physical,with various origins and controlling factors.According to logging response characteristics,the calcareous and muddy interbeds can be identified.The main interbed in this area is muddy interbed with some calcareous interbed,and it is mainly controlled by sedimentary facies, as well as the later diagenesis and faulted structure.The low porosity and permeability and sealing efect of interbeds control the oil-water distribution in the formation,which easily causes oil-water layer phenomenon.
