基于固体声弹理论的地震反射透射研究进展
Research progress on seismic reflection and transmission based on solid acoustoelasticity theory
摘要
Abstract
Multi-stage sedimentation and diagenetic processes lead to complex in situ stresses in subsurface hydrocarbon reservoirs.The in situ stresses have a broad magnitude range and their distribution directions are com-plicated,significantly impacting the rock physics properties and seismic propagation response in reservoirs.Seis-mic reflection and transmission(R/T)coefficient equations can quantify the relationship between reservoir proper-ties and observed geophysical data.Therefore,seismic R/T coefficient equations considering the effects of in situ stresses can help to better understand the characteristics of wave propagation on deep-strata stratigraphic interfaces,laying a theoretical foundation for exploring deep-strata hydrocarbon.This research topic is attracting the attention of international scholars.Most reported stress-dependent wave R/T coefficient equations consider the infinitesimal deformations induced by the in situ stress and wave perturbation based on the theory of acoustoelasticity;these ap-proaches have been preliminarily applied in several theoretical and practical scenarios such as seismic inversion for stress-induced anisotropy parameters,in situ stress detection,and discrimination of oil and gas reservoirs.In this paper,we introduce the main body of solid acoustoelasticity theory and the stress-dependent seismic R/T coeffi-cient equations based on acoustoelasticity theory,along with their basic assumptions,preliminary applications,limi-tations,and prospects in seismic exploration.关键词
