The early productivity of wells of west slope in Jinhu Sag is lower -middle -level,which is affected by the distance to the source.According to the single well perforation thickness and considering the production fluid profile split single sand body initial productivity,combined with the well sedimentary microfacies,the tectonic location,the sandstone porosity and permeability data etc.,a contrastive study was carried out to analyze the impact of the various factors on the oil well productivity.It is considered the influential factors of well productivity in west slope of Jinhu Sag main include sed-imentary microfacies,position of geological formation,reservoir physical properties,etc.The oil well productivity reduced gradually with microfacies of shore -shallow lacustrine mixing bar,shore -shallow lacustrine mixing beach,underwater distributary channel,and shallow lacustrine bar.The structural position has a great influence on the productivity.The single well oil production of all kinds of micro -phase and tectonic position increases with permeability increases,but the range of them are not same.Both the volume coefficient and formation coefficient have good control function to the well productivi-ty.%金湖凹陷西斜坡阜二段单井初期产能中等偏低，其分布规律受距物源远近的影响。根据单井射开厚度及考虑产液剖面劈分的单砂体初期产量，结合各井沉积微相、构造位置、各砂体孔渗数据等多种参数进行对比研究，分析影响金湖凹陷西斜坡油井产能的各种因素。研究认为影响西斜坡油井产能的因素主要包括沉积微相、构造位置以及储层物性等，研究区内滨湖砂坝、滨湖砂滩、残留水下分流河道、浅湖砂滩微相的储层产能逐渐变差；构造位置对产能影响较大；随渗透率的增大，各种微相及构造位置的单井采油强度增加幅度不同，容积系数和地层系数对油井产能均具有较好的控制作用。
