渗流场参数与地震波场参数的关联关系研究综述

Review of the correlation between seepage field parameters and seismic wave field parameters

地球表层岩石是由不同尺度的岩石骨架、孔隙、以及孔隙中的流体物质相互作用形成的.研究含有孔隙和裂缝的复杂岩石介质中的地震波传播效应一直是石油地球物理勘探领域的热点.因此,许多学者对复杂岩石介质的渗流特征,和地震波的传播与衰减进行了大量的研究.本文在回顾孔隙介质的地震波的传播与衰减理论发展的基础上,首先介绍了孔弹介质的非局部Biot理论,并用它预测负频散现象,然后介绍了实验观测到的波的衰减与岩石物理性质(如孔隙度和渗透率)的关系,最后,给出了对渗流场和地震波的传播与衰减的认识,并对它们之间的相互关系做了一些展望.

The rocks of earthsurface are formed by the interaction of rock skeletons, pores, and fluid matter in pores. The study of seismic wave propagation effect in porous medium containing fluid has been a hot topic in petroleum geophysical exploration. Therefore, many researchers have done a lot of research on the petrophysical characteristics of porous medium and the propagation and attenuation of seismic waves in poroelastic medium. This paper reviews the theoretical development of seismic wave propagation and attenuation in poroelastic medium. Firstly, the nonlocal Biot theory of poroelastic medium is introduced and used to predict the negative dispersion phenomenon. Then, we introduce the relationship between experimentally observed wave attenuation and rock physical properties such as porosity and permeability. Finally, we give the understanding of the propagation and attenuation of seismic wave in poroelastic medium and the understanding of reservoir porosity and permeability, and some hypothetical prospects are made for their mutual relations.
