Dual-frequency and multi-parameter IP instrument and its application research

Abstract

Variable IP method mainly measures the Percent Frequency Effect (PFE), and phase IP method mainly measures phase. They both aim at finding IP anomaly. However, only using PFE anomaly or single phase anomaly can’t distinguish IP body’s property. The authors put forward a new method—dual-frequency and multi-parameter IP method, which can not only find anomaly of PFE and phase, but also provide the property information of IP anomaly resource. The authors also have invented the dual-frequency and multi-parameter IP instrument. A lot of experiments and field work have been done. The results show that the instrument is valuable in distinguishing IP anomalies.
