摘　　要：潜山油气藏是华北油田的主要勘探领域之一。通过对任丘潜山储层的综合分析,总结了潜山内幕特征描述及储层预测的可行方法。利用三维连片处理的地震数据体,实现了潜山内幕层位的精细标定、反射特征分析和多尺度相干分析;在对潜山内幕特征分析描述的基础上,研究了潜山内幕叠后地震资料的吸收衰减补偿方法;基于地震属性分析技术,研究了潜山内幕储层或隔层的预测方法。任丘潜山实际资料的应用表明,上述研究方法在了解潜山内幕特征及储层预测方面可行且有效。Buried hill hydrocarbon reservoir is one of the main exploration areas in Huabei Oilfield.By comprehensive analysis on Renqiu buried hill reservoir,the feasible methods for interior characteristics description and reservoir prediction were summarized.Through using 3D merging processed seismic data,the fine horizon calibration, seismic reflection characteristics analysis and multi-scale coherence were carried out on buried hill layers.On the basis of analysis and description on interior characteristics,the energy absorption attenuation compensation methods for post-stack seismic data were discussed.Based on seismic attributes analysis technology,the prediction methods for interior buried hill reservoir/interlayer were studied.Case study on Renqiu buried hill indicated that the above methods are feasible and effective.
