摘　　要：综合利用测井曲线和岩心等资料,对松辽盆地南部上白垩统嫩江组三段进行沉积微相研究,划分出水下分流河道、河口坝、水下分流间湾、远沙坝和席状砂等沉积微相,建立了测井相图版。通过对研究区单井相、剖面相以及沉积微相的展布及其演化特征分析,发现水下分流河道微相为研究区的主要砂体类型。文章充分利用测井曲线信息,刻画单砂层展布规模和相带分区,为研究区下一步滚动勘探、提交油气后备储量及合理开发方案制订提供可靠的依据。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.
