摘　　要：扇三角洲前缘单期扇体垂向及平面连通关系的精细表征是复杂断块油藏描述的关键。以高分辨率层序地层学指导下的小层细分对比为基础,编制了海塔盆地贝尔凹陷呼和诺仁油田贝301区块单砂体级沉积微相图。研究表明,高分辨率层序地层学指导下的单砂体级沉积微相编图有助于从成因上解释砂体垂向及平面演化规律,准确界定单期扇体发育规模,精细刻画单砂体的展布规律,是对断陷盆地扇三角洲前缘单期扇体精细表征的有益探索。The fine characterization of the vertical and longitudinal connectivity of the single stage fan of the fan delta front was the key for reservoir description in complex fault block.Guided by the analysis of sub-layer correlation of the high resolution sequence stratigraphy,a mono-sand body sedimentary microfacies plot was compiled for Block Bei 301 of Huhenuoren Oilfield in Bei'er Depression of Haita Basin.The results show that under the guidance of high resolution sequence stratigraphy,the mono-sand body sedimentary microfacies plot is beneficial for explaining the rules of vertical and plane evolution of sand bodies,the single stage fan development scale can be accurately defined by the mono-sandbody sedimentary microfacies,the distribution rules of the monosandbody can be accurately described,it is a useful exploration for the fine characterization on the single stage fan of fan delta front of faulted basin.
