深度转化因子的选取直接影响着基于反演成像的高密度电法勘探资料处理、解释速度和精度。本文以高密度电法反演成像理论为基础,通过构建大量电阻率异常体模型,选择不同深度转化因子进行反演成像模拟,经对反演成像结果、反演速度和收敛性等综合性能的对比与分析,得到了高密度反演过程中最佳的深度转化因子。经工程实测数据验证可知,深度转化因子选0.3时反演成像精度较高、反演速度和收敛性较快。
The selection of depth conversion factors directly affects the high-density electrical prospecting data processing based on inversion imaging, explaining the speed and accuracy. Based on the high density electrical inversion imaging theory, a large number of resistivity anomalous body models are constructed, and different depth conversion factors are selected to perform inversion imaging simulation. Based on the comprehensive performance of inversion imaging results, inversion velocity and convergence Compared and analyzed, the best depth conversion factor in high-density inversion was obtained. The verification of the measured data shows that the precision of inversion imaging is better when the depth conversion factor is 0.3 and the inversion speed and convergence speed are faster.
