Abstract

The paper deduced the electrical penetration potential equation of measuring point in point-source current field from the case study of conductive sphere, and proposed the question of the relationship between the response characteristics of electrical penetration curve and spatial location of anomalous body. Comparing the response characteristics of electrical penetration curves at different spatial position anomalies shows anomalous body at shallow electrical penetration curve showed opposite electrical characteristics, its abnormal response is strongest when close to the measuring point and is weakest near the middle of the working face. The results of 3-D resistivity inversion and numerical calculation show that the effective exploration depth of electrical penetration is 30%-40% of working face width, there exist exploration weakness in the middle of the working face.
