摘　　要：通过大量的岩心观察和描述,结合沉积特征、测井、区域地质等基础资料,对安棚深层系沉积特征与沉积相进行了全面的分析,认为安棚深层系属近源快速堆积的扇三角洲沉积体系,共划分为9种岩相特征;在砂岩和砾岩中发育平行层理、斜层理、块状层理;主要发育水下分流河道、河口坝、席状砂等微相。明确了不同时期、不同砂体的沉积微相展布特征,同时与冲积扇沉积体系进行对比研究。在对扇三角洲的形成条件、岩性特征、沉积微相特征分析的基础上,研究了扇三角洲的识别标志,并建立了扇三角洲的沉积模式。Through a lot of core observation and description,combining with the sedimentary characteristics,logging data and regional geological data,the comprehensive analysis of sedimentary characteristics and sedimentary facies in deep strata series of Anpeng oilfield was carried out.The results indicated the region belonged to fan delta sedimentary system and had 9 kinds of lithofacies.In sandstone and conglomerate,parallel bedding,oblique bedding and massive bedding were mainly developed.There mainly developed underwater distributary channel,mouth bar,sheet sand microfacies,etc.The sedimentary microfacies distribution characteristics of different sand bodies at different periods were made clear and compared with that of in alluvial fan sedimentary system.Based on forming conditions,lithologic features and sedimentary microfacies analysis of fan delta,the study on identification mark of the fan delta was carried out and its sedimentary model was established.
