TI介质地震波传播特征与正演方法研究 

地球介质广泛存在波动各向异性,地震各向异性主要表现为地震波传播速度是传播方向的函数、体波间的相互耦合、横波发生分裂等。地震各向异性研究已经成为地震学研究领域中的前沿课题之一,开展地震各向异性研究对认知地球介质结构、勘探开发复杂油气藏和预报地质灾害均具有理论意义和实用价值。 各向异性是沉积岩石中几乎...

粘弹TI介质单程波正演模拟与反Q偏移研究 

实验已经证明实际地下介质是非完全弹性介质,并且广泛存在着各向异性,地震波在实际地下介质中传播时往往要同时受到粘弹性和各向异性的影响。因此,对于地震勘探方法技术不断向高精度方向倾斜的今日,粘弹性和各向异性问题早已不再是一个没有实际意义的学术研究课题,而是地震勘探理论和方法研究中的一个关键因素。如果继续忽略粘弹性和各向异性...

部分饱和多相介质中Rayleigh面波传播特性研究 

Rayleigh面波在很多领域都显示着重要的作用,比如地震学、地下水、工程、环境、地质学和材料科学。英国学者Lord Rayleigh于1885年首先在理论上发现并证实了,在各向同性均匀弹性介质中Rayleigh面波的存在。这种波沿着自由界面传播,如地球和空气界面,它是纵波和横波的干涉波,并且总是在地震记录中显示出强振...
