| 摘 要： | 在有限元点源二维电阻率正演基础上,针对传统对称四极装置其电极距跨度大且不等间隔分布等特点,提出将整个正演计算区域划分为目标区、观测区和扩展区三个区域,在观测区域先采用等间隔剖分,然后在区域中插入实际电极作为正演计算节点的剖分方式,同时将无穷远边界条件简化技术引入到正演计算中,并结合人机交互与可视化技术实现了大极距电阻率/激电测深的二维正演模拟。最后通过对相关模型的试算结果表明,作者在本文中提出的针对传统对称四极装置电阻率/激电测深的二维正演模拟技术是有效可行的。

| Abstract: | On the basis of the FEM forward modeling for a point-source on a 2-D structure and with the Sclumberger electrode array featuring large and uneven distributed electrode-spacing considered, a 2D forward modeling has been realized for resistivity/IP sounding of large electrode-spacing by dividing the whole calculation area into 3 zones, i.e. target, observation and expended zones. The observation zone is gridded evenly at first and the points of electrodes are inserted as calculation nodes afterwards. At the same time, the method of simplifying infinite boundary condition, along with man-machine interactive and visualization techniques, is also introduced into the calculation. The results of test calculations show that the 2D forward modeling proposed is effective. |
