摘　　要：为解决储层研究中资料分散、联系不紧密、定量化标准和一致规律性缺乏等问题,应用储层地质知识库理论,以大庆长垣油田喇萨区块葡一组辫状河储层为例,利用密井网测井、沉积、物性分析和卫星照片等资料,分析储层砂体层次类型和规模,对比辫状河和心滩坝的充填样式和定量规模;根据辫状河道砂体储层构型要素和几何特征,构建辫状河储层地质知识库.结果表明:大庆长垣喇萨区块葡一组辫状河储层分为古河床范围砂体带(五级)、辫状河单砂体(四级)和落淤层(三级)3个构型单元级次;按照充填样式、定量规模和物性特征,划分辫状河单砂体的辫状河道和心滩坝2个构型要素.该研究结果获得辫状河沉积储层不同级次的构型要素与砂体的规模、方向、几何形态及厚度等定量地质知识,为提供类似区块辫状河储层地质建模和预测提供指导.In order to overcome in the study of reservoir data dispersion and contact close enough,the lack of quantitative standard,as well as the problems such as difficult to unified understanding regularity,reservoir geologic knowledge base is established.In Daqing Changyuan demodex La-Sa piece of Putaohua,for example,a set of reservoir by using dense well pattern in the area of well logging,sedi-mentary and satellite photos,physical properties,such as data,describe the braided river sand body types,analysis of braided river style,the heart is filling the identification method,the channel sand body of beach dam reservoir configuration elements and geometric features,braided river reservoir geologic knowledge base is established.Results obtained the braided river sedimentary sand body with the different levels of configuration elements of size and thickness direction,geometry and quantitative geological knowledge,to guide similar block of braided river reservoir research,prediction and geological modeling provides quantitative parameters have important reference value.
