摘要
本文从频谱分解技术的基本原理及计算方法入手,根据正演模型,通过对比缝洞型储层与地震反射特征的关系,总结出储层发育的反射特征,相应地精细调整频谱分解处理参数,进而进行预测。通过与钻井资料对比可知,频谱分解技术可以刻画不同频率强反射、弱反射的边界。
Coming from the basic principle and algorithm of spectrum factorization technique and based on forward model,the paper summarized the reflected feature of reservoir development by correlation of relationship between the fracture-vuggy reservoir and seismic reflection feature,finely adjusted the processing parameters of spectral factorization accordingly and then made prediction.It is known by correlation with drilling data that the spectral factorization can describe the boundaries of strong reflection and weak reflection in different frequencies.
