VSP正反演综述

Review on the forward modeling and inversion of vertical seismic profile

垂直地震剖面法是一种发展很迅速的地球物理方法,由于垂直地震剖面法是在介质内部点上直接观测,因而能够避开或减弱剖面上部低速带的干扰及外界噪声干扰,可以更直接、更有效地研究波的运动学和动力学特征,解决其地质问题,因此在地球物理勘探领域中最为活跃.本文从垂直地震剖面正反演的角度,并结合国内外实际的例子来介绍垂直地震剖面,同时讨论了垂直地震剖面未来发展的方向.

Vertical seismic profiling（VSP） is a rapidly developing technology.Because VSP offers the possibility to analyze reflected and transmitted seismic waves generated by a source located at the surface and recorded by geophones positioned in a borehole.Compared with surface seismic technology,VSP has a higher S/N ratio and resolution,and its waves＇ motive and dynamic characteristics are more conspicuous,so it plays an important role in exploration seismology.This paper introduces the simulation and inversion of VSP and gives the prospect of VSP.
