| 摘 要： | 对新疆库木库里盆地的一条大地电磁测深剖面(2005-C)通过频点加密的处理后,获得比常规处理频段更宽的视电阻率和相位资料,采用NLCG二维反演新技术对原始加密频点的视电阻率和阻抗相位资料进行约束反演,通过与常规频段的连续介质反演、RRI二维反演结果比较分析,寻找适合本测区电性结构的最佳反演方法;同时,结合有限的区域地质资料和2005年同期完成的盆地内物性资料,对库木库里盆地新生代地层二维电性结构形态、盆地地层格架及第三系埋深进行了较为可靠的推断。

| Abstract: | In this paper, after one magneto telluric sounding profile （2005--C） of Kumukuli basin is analyzed through high--density, a wider apparent resitivity and electromagnetic da- ta than common ones are obtained. By means of several kinds of 2D inversion new methods （RRI,NLGG etc. ）, a better inversion method for interpretation is found, and a depending horizontal 2D geoelectric structure along 2005--C profile is obtained. Meanwhile, the limit- ed regional geophysical data are combined with that of 2005. Through the data, shape of basin, fault characteristics, the spatial distribution regularity of geoelectric structure of this basin, and the depths of the lithology of system are deduced clearly. |
