摘要

随着地震勘探的发展,在处理复杂的孔洞性地质构造时,常规反射波模拟方法出现了局限性。于是,针对孔洞性非均匀介质的散射波模拟方法发展起来。通过基于Green函数的积分方法来正演模拟孔洞性介质的地震波散射波场,了解其波场特征,分析物性参数对于孔洞性介质散射波场特征的影响,对油气的勘探开发具有十分重要的意义。
With the development of seismic exploration,conventional reflection simulation method shows limitation in processing complex porous geologic structure,thus developed scattered wave simulation aiming at heterogeneous porous media.Seismic scattered wave field of porous medium has been forwardly simulated by using integration method based on Green's function;the effect of petrophysical parameters on scattered wave field has been analyzed.This study is of important significance to oil and gas exploration and development.
