This paper is concerned about the study of well logging sedimentary facies of East Fukang Slope in Junggar Basin.It mainly applied common well logging data,dip logging data and image logging data to analyse and define the sediment and the sedimentary facies.The treatment of ANN lithofacies showed that typical delta facies included delta-front distal bar,mouth bar,subaqueous branch channel,interdistributary estuary,delta-plain branch channnel and interbranch channnel in ascending order.The correlation of lithofacies and logging section showed almost no difference,which contributed to the analysis of facies sequence and sedimentary system in the region.The definition of paleocurrent system showed that sediment source was mainly located in the north of Kelameili Montain, and there was a minor sediment source in the south of Beisantai region during Badaowan and Sangonghe formations deposited.In the end,Comprehending the lithologic section from the treatment and interpretation of common well logging data,the interpretation results of sedimentologic dip logging(including sedimentary structure and paleocurrent) on base of the core correction and ANN treatment results,we established the well logging sedimentary parfacies and minifacies model of Jurassic system in key well in East Fukang Slope.
