摘要 在油气勘探中,影响地震属性方位角变化的因素除了裂缝的方向和密度因素外,还有储层岩性的差异、构造、应力场的分布和饱和流体的成分等。要描述裂缝在空间的分布密度,往往需要综合分析地震资料并考虑可能的地质因素和力学特征的影响。为此,提出将信息融合技术应用于裂缝密度的综合预测,并具体介绍了信息融合技术的概念和优点,重点阐述了线性融合法及实现步骤,并应用于实际,效果良好。 In oil and gas exploration, azimuth variations of the seismic attribute are affected not only by fracture orientation and fracture intensity, but also by reservoir lithologic differences, structure and stress field distribution, saturation fluid contents and so on. In order to delineate fracture spatial distribution intensity, we have to comprehensively analyze seismic data, and meanwhile take the influence of possible geologic factors and mechanical behaviors into consideration. Therefore, the paper introduced how this information fusion technology was applied to the integrative prediction on the fracture intensity, and described in detail the concept and advantages of information fusion technology, and focused on the linear information fusion method and its implementing approaches. A good result was obtained for this method used in actual field production.
