在露头研究、岩心分析的基础上 ,在双河油田建立了不同于 Miall划分方案的 6级界面系列 ,总结了 7种基本结构要素 (水下分流道、河口坝、水下溢岸、前缘席状砂、重力流、水下决口扇、湖相泥 )的特征及测井响应 .通过储层精细对比 ,建立了双河油田核三段 I- IV油组的储层建筑结构预测模型 ,总结了建立地下储层建筑结构模型的方法和基本步骤 .模型表明扇三角洲平面模型具有分带性 ,剖面模型则可分为分流河道型、分流河道与河口坝型、席状砂型、递变型 .建筑结构模型可用于建立储层精细流动单元模型或结合开发动态 ,据此可直接进行剩余油分布分析
Based on the outcrop study and core analysis, a series of 6-level interface series different from the Miall classification scheme were established in Shuanghe Oilfield. Seven basic structural elements (underwater distributary channel, estuary dam, underwater overflow, Sedimentary sand, gravity flow, underwater mouth fan, mud of lake facies) and well logging response.According to the fine reservoir contrast, the prediction model of reservoir building structure of the third member of the I-IV oil group in the Shuanghe Oilfield is established, The methods and basic steps of building structural model of underground reservoir are summarized.The model shows that the fan delta plane model has zonality, and the profile model can be divided into distributary channel type, distributary channel and estuary dam type, sheet sand type and transition type. Building structural models can be used to model the formation of fine-flow units in the reservoir or in conjunction with development dynamics, allowing for direct analysis of residual oil distribution
