摘　　要：从区域地质背景出发,结合岩心、测井等资料,通过岩相类型、粒度分析、测井相分析等对沉积相标志进行了综合研究。认为该区主要发育浅水辫状河三角洲沉积,其中,分流河道、心滩、分流河道间、水下分流河道、分支间湾、前缘席状砂、河口坝等7种微相较为发育。对不同的沉积微相特征进行了分析,并建立了该区沉积相模式,为油藏的勘探开发提供了重要的地质依据。Various facies marks,such as facies types,grain size distribution patterns,electrofacies,and regional geological settings,have been carefully studied for the Hongnan 9 Block of the Honglian Oilfield.The results show that this area was once occupied by a shallow braided deltaic system,consisting of distributary channels,channel bars,interchannel bars,subaqueous distributary channels,branched bars,sheet sands,and mouth bars.A sedimentary model was established for the Block upon the studies mentioned above.The model could be used as an important tool for reservoir exploration and development.
