【摘要】 以长春岭背斜带登娄库组为例,基于频率补偿原理,应用自然伽马高频分量和波阻抗曲线的低频成分构建拟波阻抗曲线;通过测井曲线标准化、地震资料预处理、子波标定及地震合成记录、地质模型等,实现长春岭背斜带登娄库组储层预测.结果表明,基于低频补偿、高频恢复构建拟波阻抗曲线的重构方法的反演结果能够识别5 m左右的薄砂岩,结合沉积地质认识,能够刻画登一段砂体的空间展布,为后期储层预测提供依据.更多还原

【Abstract】 Thin-layer reservoir prediction is poses great difficulties in seismic prospecting.With the research of Denglouku Group of Changchunling anticlinal zone,we use frequency compensation theory to build pseudo-acoustic curve in order to realize the seismic inversion of Denglouku Group through some important links such as standardized processing of logging curves,seismic data preconditioning,calibration of seismic wavelet,synthetic seismogram and geological modeling.After reconstructing,the result can identify sand body for more than 5m’s thick.Combined with the knowledge of sedimentary geology,we describe the spatial distribution of the Deng-I segment sand-body,which provides the reliable basis for later analysis.更多还原
