【摘要】 在以地震反射特征分析为主的三维地震综合定性识别缝洞技术方法的基础上,利用地震多属性优化分析技术建立了6个亚类的地震反射特征量化识别模板。首次采用计算机误差反向传播神经网络技术自动量化识别6个亚类特征的储集体,并预测储集体空间分布。该方法在塔河油田碳酸盐岩油藏缝洞量化描述和开发部署中的应用效果较好,已成为"十二五"塔河缝洞型油藏定量描述的主要方法之一。更多还原

【Abstract】 Based on seismic reflection characteristics of integrated three-dimensional seismic qualitative identification for fracture-cavity reservoirs,seismic multi-attribute optimization analysis techniques was used to establish a quantitative recognition template of seismic reflection characteristics of the six sub-categories.For the first time a computer error back-propagation neural network technology was used to automatically quantify,identify six sub-categories of the reservoirs and predict the spatial distribution of reservoirs.Good result is obtained in field application in Tahe Oilfield,it becomes one of the key methods for fracture-cavity reservoir description in Tahe Oilfield in the 12 TH National 5Year Plan.更多还原
