Occam二维反演方法在安徽庐枞盆地某矿区CSAMT资料处理中的应用

The Application of 2D Occam Inversion in CSAMT Data Processing for a Mine Area in the Luzong Basin

Occam二维反演方法经常应用于大地电磁测深数据的反演计算中,而在CSAMT资料处理中,应用则相对较少。为探讨Occam反演方法对CSAMT数据的反演效果,设计了两个理论模型,以检验Occam二维反演的效果。反演结果表明,Occam二维反演具有稳定的收敛性,能够很好地还原理论模型。在安徽庐枞盆地某矿区中应用Occam二维反演方法对CSAMT数据进行了反演,其反演结果与钻探资料吻合较好,证明该方法具有很好的应用效果。

Occam 2 D inversion method is often used in audio frequency magnetotelluric sounding data,and in the CSAMT data processing,it’s not widely used. In order to know the inversion result of occam,in this paper,the author designs two theory models,and shows that Occam 2 D inversion is stable and convergent,also can restore the models. The inversion of CSAMT data is carried out in a mining area of Luzong basin in Anhui by Occam 2-D inversion method. The inversion result is in good agreement with drilling data,which proves that the method has good application effect.
