重力勘探中位场增强新方法

实测异常往往因受到外界环境的影响而导致其形态特征不明显,从而无法准确地得到异常体的位置、范围、走向等信息.针对该问题,人们提出了很多方法来使异常特征明显化,如阴影图、分析信号、斜导数法等,以上方法都能很好的完成这项操作.本文提出了高低帽变换和小波分析方法来进行异常形态特征增强,通过实测数据的处理结果可以看出,这两种方法...

A new method for enhancing potential field in gravity exploration

The morphological characteristics of the external environment,which can not accurately be abnormal body position,range,direction and other information.According to the above mentioned problem,many methods have been proposed to make clear of anomalies,such as shadow maps,analysis of the signal,oblique derivative method;the above methods can be very easy to complete this operation.In this paper,the high-low peak transform and wavelet analysis method have been proposed to enhance abnormal morphological feature...
