地震虚源法技术
|
摘要
为应对地震成像中上覆层的复杂性问题,R.Calvert和A.Bakulin提出虚震源法,用于近地表精确速度建模。笔者阐述了地震虚源法的原理,与井间地震技术的对比,国外在时移地震监测、成像和虚横波源等三个方面的应用现状。文章将对有关人员了解该技术起到一定帮助指导作用。
In order to tackle the problem of complex overburden formation,R.Calvert and A Bakulin of Shell developed the virtual source method,which can solve the problem of building accurate velocity model.In this paper,the authors have dealt with the principle of virtual source,made a comparison with the crosswell seismic technology,and described its application in such aspects as time-lapse monitoring,imaging and virtual-shear wave.The results can provide some guidance for the understanding of this method.
