水平电偶源r方向电场值应用的理论研究
THE THEORETICAL STUDY OF r-DIRECTION ELECTRIC FIELD VALUE APPLICATION OF THE HORIZONTAL ELECTRIC DIPOLE
摘要
Abstract
Depending on the formula of electromagnetic field data from horizontal electric dipole under the quasi-static conditions, this paper deals with the measurement sector and advantages of electric field r-direction. Through numerical calculation of several typical layered models such as D, G, H and K, the Er apparent resistivity is compared with the Ex apparent resistivity under 1-D conditions. The result shows that the measuring position has less effect on Er apparent resistivity. Through numerical calculation of a single anoma-lous body existent in half-space by using the integral equation method, the Er apparent resistivity is compared with the Ex apparent re-sistivity under 3-D conditions. The result shows that the Er apparent resistivity has a better effect on the edge of the low-resistivity anom-alous body.关键词
