摘要
简述了中生代断陷湖盆陡坡发育的近岸水下扇识别标志、各亚相和微相的沉积特征，提出了水进型近岸水下扇的垂向沉积序列和沉积模式，评价了近岸水下扇各微相砂体的储集性能，指出了富集油气的沉积微相类型．
This paper describes briefly the sedimentary features of each subfacies andmicrofacies in a nearshore subaqueous fan located at a steep slope of Mesozoic faulted- down lacustrine basin. A vertical sequence and a sedimentary lnodel of the nearshore subaqueousfan are developed.The reservoir capacity of each microfacies sandbodies in the nearshoresubaqueous fan were evaluated.The types of microfacies with rich oil and gas are presented.
