摘要
地球物理反演是利用观测数据恢复地下地质结构和岩石性质的方法。介绍了地震反演技术从直接反演到模型反演,从线性反演到非线性反演,以及从叠后反演到叠前反演的发展过程。弹性波阻抗反演的出现将成为反演进一步发展的方向之一,地震反演正走向声波波阻抗与弹性波阻抗相结合的道路。
Abstract
Geophysical inversion is a computational process to restore subsurface geological structures and petrophysical properties from observed geophysical data.This paper outlined the evolution of seismic inversion technologies, from direct inversion tomodel based inversion, from linear inversion to nonlinear inversion, and from poststack inversion to prestack inversion. The inversion of elastic impedance will be one of directions of inversion development.Seismic inversion is on the way of integrating acoustic impedance with elastic impedance.
