各向异性介质中利用弹性参数进行岩性勘探的设想

TENTATIVE IDEAS FOR LITHOLOGY INVESTIGATION IN INHOMOGENEOUS MEDIUM BY USE OF ELASTIC PARAMETERS

长春地质学院

本文强调了介质的各向异性对地震波的影响,并提出了以介质的弹性参数为特征量,利用模糊数学的概念进行岩性勘探的设想.为此,作者介绍了利用t²-x²曲线的三阶泰勒序列获取弹性参数的方法.

By taking the effect of inhomogeneity of medium on seismic wave into full account, the tentative ideas for lithology investigation by using the elastic parameters of the medium as the characteristic variables and by useing the fuzzy theory as the tool were presented. In order to attain this goal, the extraction of the clastic parameters by utilizing the third order Taylor series of t2-x2 was introduced in this connection.
