Test of Source-Parameter Inversion of Intensity Data
      
The multi-parameter inversion of elastic wave equation in a half-space within the Born approximation is studied.
      
The specific procedure is to conduct a 2D interface-constrained CEMP inversion using 2D seismic and log data followed by a property parameter inversion of the anomalous bodies using gravity and seismic data by the stripping technique.
      
Then, using multi-parameter inversion and integrated multi-attribute analysis, we predict the favorable reservoir distribution quantitatively and setni-quantitatively to clarify the distribution of high-yield zones.

The simultaneous inversion of pressure wave impedance and sear wave impedance for the elastic layered media is discussed. The elastic wavefield excited by the line source of pressure wave can be decomposed into the plane waves, which correspond to the different angles of incidence. The propagation of the plane elastic waves is governed by the system of one-dimensional equations derived from the fundamental equations of elastic wave. From this system for a fixed angle of incidence two parameters of the elastic...

The simultaneous inversion of pressure wave impedance and sear wave impedance for the elastic layered media is discussed. The elastic wavefield excited by the line source of pressure wave can be decomposed into the plane waves, which correspond to the different angles of incidence. The propagation of the plane elastic waves is governed by the system of one-dimensional equations derived from the fundamental equations of elastic wave. From this system for a fixed angle of incidence two parameters of the elastic layered medium can be determined by using the surface data of the vertical and horizontal components of the displacement velocity. On the assumption that the density is known, then the impedance of pressure wave and the impedance of sear wave can be determined. In the paper the formulation of two-parameter inversion problem(IIP) is presented, the characteristic difference schemes for solving IIP are constructed and some numerical experiments are performed. The numerical results show that the impedance of pressure wave can be successfully determined.

讨论层状弹性介质的纵波阻抗和横波阻抗的同时反演问题.由纵波线源激发产生的弹性波场,通过倾斜叠加可以得到其平面波分解,分解出来的平面波场对应于以不同倾角斜入射激发所产生的波场,它们满足由二维弹性波基本方程派生出的一维偏微分方程组.利用在地面同时接收的位移速度的水平和垂直分量,可以由每个特定角度斜入射产生的平面波场所满足的一维方程组反演层状弹性介质的两个参数,在已知密度情况下,可以反演纵波阻抗和横波阻抗.本文给出了这个反演问题的提法,构造了求解此问题的特征线差分格式,并计算了一些数值例子.数值结果表明纵波阻抗的反演是成功的.

The reflection wave seismogram is made use of recovering two paramaters from wave equation in order to research the subsurface structure. This is one of the popular topic on geophysical application. In this paper, the new method of discerning two important paramaters medium density and wave velocity is deduced on the basis of the theory about the inversion method of one-parameter inversion from wave equation and is applied successfully to the calculation of theoretical model and real logging data. This method omitted Green fUnction. The amount of Calculation is decreased greatly and its application is increased.

利用反射波地震记录恢复波动方程的两个系数以研究地球内部构造,是当前应用地球物理研究的热点之一。本文在波动方程反演方法的理论基础上,导出了频率域识别介质的密度,波速两个重要参数的新算法。从而把当前的波动方程单参数反演方法推广为双参数反演方法。通过理论模型及实际测井资料的反演试算对比,均获得良好效果。在算法中还省去了Green函数的繁杂计算,节省了计算量,增加实用性。
