Title: Application of electrofacies in sedimentary microfacies analysis for the third member of the Nenjiang formation in southern Songliao Basin
Abstract: The sedimentary microfacies of the third member of upper Cretaceous Nenjiang formation in southern Songliao Basin are studied and recognized by comprehensively using logging curves and core data,including underwater distributary channel,debouch bar,underwater interdistributary embayment,distal bar,and sheet sand.The chart of logging facies has been set up.The distribution and evolution of single well facies,profile facies and sedimentary microfacies are analyzed,and it is found that the main type of sand body in the study area is underwater distributary channel.This research makes full use of well logging information to delineate single-sand distribution and facies partition,provides reliable basis for progressive exploration,discovering backup reserves,and formulating reasonable development plan.
