摘要
在以往的高密度数据反演解释过程中,将地质结构简化成二维,通过地电断面图、切片图进行分析。实际上,地质体具有三维地电结构,二维反演难免会受到旁侧效应的影响,二维图件也不能清晰直观地反映地质体的空间分布情况。本文以某陶瓷厂空洞探测为例,利用实测资料构建三维数据场,在反演参数优化的基础上,选择基于最小二乘法的三维反演技术对数据场进行处理,将反演结果利用三维可视化技术显示出来,对采空区位置及空间形态给出结论。研究结果显示,三维处理技术能够从空间上,多手段、多视角分析物探数据,有效地消除了旁侧效应的影响;物探结果直观清晰地呈现出空洞的分布位置、范围以及空间特征,与钻探结果吻合较好。
This paper uses the measured high density resistivity data to build 3-D data field.It chooses the 3-D inversion technique in association with the least squares method to process the data field after inversion parameter optimization.The inversion results are presented using 3-D visualization imaging technology.The results show that the use of 3-D processing technology can analyze the geophysical data spatially through multi-tool and multi-angle and can effectively eliminate the influence of the side effects.Geophysical results are more intuitive,clear and easy for analysis and interpretation.Finally,using drilling information,the accuracy and advancement of 3-D data processing technology are proved.
