摘要
当地表浅层存在不均匀地质体时,会发生静态效应,对大地电磁测深数据资料产生畸变影响,从而影响到后期的资料处理和解释。本文运用有限单元法计算大地电磁测深二维正演,通过建立不同模型得到的响应特征,分析静态效应对大地电磁测深数据的影响。
When the inhomogeneous geological bodies exist in the shallow ground, the static effect will occur, which will have the distortion effect on magnetotelluric sounding data, thus affecting the later data processing and interpretation. This paper calculates the two-dimensional magnetotelluric forward modeling using the finite element method, and analyzes the influence of static effects on magnetotelluric sounding data based on the response characteristics of establishing different models.
