摘要
提出了基于Smooth+LCI的拟二维反演方法,根据Tikhonov正则化反演理论以及横向约束理论LCI,利用Smooth反演法,通过二维阵列式线圈的工作模式,将所有核磁信号从一侧产生横向和纵向的LCI平滑过渡,实现了核磁共振拟二维反演。相比传统的反演法,得到对中、深层更精准的含水层位置和含水量信息,稳定性更好。
Based on the Tikhonov regularized inversion theory and Laterally Constrained Inversion,using the method of Smooth inversion and the operating mode of a two-dimensional arrayed coils, all the NMR signals have produced the transverse and longitudinal LCI smooth transition from one side that achieves NMR inversion. Compared to traditional inversion method, this method can achieve the more accurate information of the middle and deep aquifers′ location and water content information, and has better stability.
