| 摘 要： | 通过对卫城油田卫22块铸体薄片、扫描电镜以及孔隙度渗透率资料的分析,对研究区储层微观非均质性,储层层内、层间、平面非均质性做了详细的研究。认为研究区储层砂岩以细砂岩粉砂岩为主,孔喉结构为中孔细喉;储层非均质性主要受控于沉积作用和成岩作用,层内渗透率大部分为反韵律序列,各小层内部渗透率的差异性很大,表现为严重非均质型;纵向上各小层砂岩密度相差很大,但各井垂向上渗透率差异不大,以非均质型居多;平面上储层非均质性主要受沉积相带平面分布的影响,水下分流河道和河口砂坝沉积非均质性较弱,前缘沙席表现为较强的平面非均质性。

| Abstract: | Based on the data of thin section,SEM photos,porosity and permeability,this paper focuses on a detailed study of micro heterogeneity,in-layer heterogeneity,interlayer heterogeneity and plane heterogeneity about the reservoir of wei22 block,weicheng oilfield.The result shows that feldspar-quartz sandstone is the main rock type in this region,with medium pore and fine throat.The reservoir heterogeneity is mainly controlled by sedimentation and diagenesis.Most of in-layer permeability is anti-rhythm sequence.T... |
