中梯装置主剖面非均匀场异常物理模拟及校正

Physical simulation and correction to field anomalies on non-uniform main section of intermediate gradient device

通过水槽电法物理模拟研究了中梯装置主剖面非均匀场异常,并进行了校正试验,模拟研究表明:中梯装置测量剖面视电阻率需要校正,中梯装置实际测量区间可以扩展到2/3AB区间。

Through sink electrical physical simulation, it studies the field anomalies on non-uniform main section of intermediate gradient device, and carries on calibration test. Simulation studies show that： intermediate gradient device surveying main section apparent resistivity needs correction, actual measurement interval of intermediate gradient device can be extended to 2/3AB range.
