In this paper, seismic inversion of elastic parameters in horizontally layered VTI ( transverse isotropy media with vertical symmetry axis) is well studied, on the basis of seismic wave kinematics theories in transverse isotropic media with vertical symmetry axis. 根据地震波在具有垂直对称轴的横向各向同性(VTI)介质中的运动学特征,应用传播时间反演方法,进行了水平层状VTI介质的地层弹性参数反演方法研究。
Some numerical examples show that the inversion results are in much good agreement with the true conductivity profile by dual induction tools measurements at the axis points. 一些数值例子表明,只利用双感应测井信号也能很好地反演出地层电导率径向剖面,且反演结果与真实电导率剖面分布吻合得相当好。
The theory of finite Hankel transform and its inversion formula were founded and some properties of finite Hankel transform were proved. By this theory, the general solution of symmetric stress system on axis with finite diameter was got. 建立了有限Hankel变换及反演变换理论,证明了有限Hankel变换的若干性质,利用有限Hankel变换给出了有限直径轴对称应力系统的一般解。
