摘要
阻抗张量模具有多维信息综合和降维的优势,适用于基于严格意义上的一维地电断面情况下拟地震反演法,相比单个阻抗要素反演,可更多地凸显地质体在横向和纵向上的电性分界面,同时又具有最小构造的特性.因此,反演所得反射系数时间剖面不仅可用于判断极化模式和给定二维电阻率反演的初始模型,还可用于优选反演结果模型;在解释时可弥补常规大地电磁资料反演所得电阻率的模糊像,对划分电性层,推断隐伏断层的位置等都具有重要的实际应用意义.并将该方法用于中上扬子油气勘探大地电磁资料处理中,取得了较好的效果,方法具有一定实用价值和应用前景.
Pseudo-Seismic Interpretation of MT(PSI)is based on the ID geoelectric section,But the transverse magnetic(TM) and transverse electric(TE) modes of the 2-D and approximately 3-D magnetotelluric field was different,i.e.the TE mode is more sensitive to the deep structures,the TM mode may be more sensitive to the near-surface structures and lateral inhomogeneous body.So the result of the reflection coefficients of EM wave with TM or TE modes using PSI was different.In some sense,the impedance tensor determinant is TE and TM modes comprehensive expression,It may instead of TE or TM modes inverse the reflection coefficients by PSI method,and the time cross-section satisfy the principle of information complementarity,the results can taken as the initial model in 2-D resistivity inversion,and preferred inversion model.In integrated geological/geophysical interpretation terms,the time cross-section of reflection coefficients would help us divide the electrical interface and deduce the underlying fault,etc.We apply this method to interpretation of magnetotelluric sounding data of hydrocarbon exploration somewhere in southern China,and get satisfactory results.
