摘要

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.

Abstract: 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.
