摘要
本次研究综合应用成像测井和岩心资料来识别裂缝。从井震联合层位标定入手,以弹性参数特征分析为基础,利用叠前地震资料,建立裂缝地震响应模式,分析裂缝各向异性对应的地震属性变化规律,用地震叠前叠后多属性预测的裂缝进行约束和验证,通过分方位角各向异性分析,裂缝参数计算,优选地震属性,获得裂缝展布方位和发育密度等参数。
Imaging logging and core data are applied in this paper to recognize fractures. The fracture earthquake response mode is established on the basis of on the characteristics of elastic parameters and pre-stack seismic data as well as the well-seismic joint horizon calibration. The changes of seismic attributes corresponded to crack anisotropy are analyzed. The fractures predicted by pre- and post-stack seismic multi-attribute are restrained and verified through analysis on azimuthal anisotropy,calculating parameters and optimizing seismic attributes to obtain fracture parameters such as spread orientation,development density.
