<p>This invention involves a method and an apparatus for measuring the electromagnetic wave resistivity of the earth, which samples data from strata with an electric field sensor, a magnetic field sensor and a data collection system connected to them, implements collection controlling, data storage and processing on the sampling data according to a basic relational expression between a strata depth (H) and a propagation frequency (F) and a basic relational expression between the electromagnetic wave resistivity (p) and the strata depth (H), and realizes continuous measurement of the electromagnetic wave resistivity of the earth. The invention directly calibrates the relationship between the propagation frequency and the strata depth by using actual data, modifies the traditional method which may obtain the depth or thickness of strata by using multi-variable theoretical formula so as to make the resistivity of the strata as a unique variable. This method of the invention greatly improves the precision of measured depth of electromagnetic wave. The method and the apparatus may process the collected data on-the-spot, and obtain the curves of the electromagnetic wave which varies with the depth at any time. The method and the apparatus of the invention can be directly used to explore mineral resources with the effect of decreasing the number of drill well and increasing the overall exploration benefits.</p> |
