摘　　要：濮城油田Es2^上油藏断块构造复杂，储层非均质性严重，为低孔、低渗油藏。为了更好地确定剩余油分布规律，将储层沉积相研究深入到沉积微相。通过岩心、测井、地震资料识别沉积相标志，确定Es2^上为三角洲前缘亚相沉积，并对其沉积微相特征及分布规律进行了研究，确定了有利于油气聚集的沉积微相类型。最终结合区域沉积背景，总结了本区三角洲前缘亚相的相层序及相模式。Es_2up reservoir in Pucheng Oilfield is complex in structure,highly heterogeneous,low porosity and low permeability.The study on sedimentary facies has been deepened into microfacies to better understand resid- ual oil distribution.Sedimentary markers are defined by coring,logging and seismic data.Es_2up reservoir is i- dentified as delta front intrafacies and studied for its sedimentary microfacies and distribution pattern.Favorable microfacies of hydrocarbon accumulation are delineated.Finally,the facies sequence and facies pattern of the delta front intrafacies in this area are generalized combining with regional depositional setting.
