摘要
常规磁性基底反演方法往往忽略基底磁性变化采用常磁化强度模型,这里分析了其中的局限性,提出了先构建相关搜索重磁三维定量反演技术的变磁化强度模型,然后通过Parker界面反演算法进行基底反演。其中,对反演磁化强度所需磁异常分离采用了小波变换方法,并分析了该方法的关键技术和措施。通过利用该方法对某工区进行了实际资料处理后,得到较好效果。
Conventional magnetic basal inversion method often ignored the magnetized basement magnetic change,this paper analyzes the limitation of the method,and puts forward that before constructing the relevant search quantitative inversion technology of 3D model,variable magnetized strength model should be built,then using Parker interface inversion algorithm for basal inversion.The intensity of magnetic anomaly inversion magnetized required separation adopted wavelet transform method.The key technology and measures of this method is analyzed.A project of the actual data was processed by using this method,and the better results were gotten.
