摘要
通过对S气藏含砾砂岩段岩心观察和测井资料统计分析,结合砂体和沉积相的展布特征,对研究区含砾砂岩段储层的层间、层内、平面非均质性进行研究。认为研究区储层非均质性主要受沉积作用的控制,储层层间非均质性程度中等—强,由于渗透率韵律的多样性使各小层层内非均质性程度不一,整体为中等—强非均质性,储层平面非均质性主要受沉积相带平面分布的影响,泥坪相所在区域非均质性较弱,而潮汐砂坝和潮控河道表现为中等—强的平面非均质性。
Based on core observation, well logging data statistical analysis of pebbly sandstone formation in S gas reser- voir, and combined with sand and sedimentary facies distribution, this paper focuses on a detailed study of interlayer heterogeneity, in - layer heterogeneity and plane het - erogeneity about the reservoir of pebbly sandstone formation . The result shows that the reservoir＇s heterogeneity is controlled by the distribution of the sedimentary, facies. The interlayer heterogeneity is medium to strong, due to the diversity of permeability rhythmic in single layers, the heterogeneity is dif- ferent from each uther, for the overall is medium to strong heterogeneity, the Plane heterogeneity is mainly controlled by the sedimentary facies distribution, the re, on of mud flat heterogeneity is weak, the tidal bar and tidal river channel performance medium to strong plane heterogeneity. Based on the roservoir heterogeneity research which can guide the de- velopment adjustment scheme, it is offer help for reservoir efficient development.
