METHOD OF MODELLING IN INDUCTANCE GEOLOGICAL ELECTRONIC RECONNAISSANCE Russian patent published in 1994 - IPC

FIELD: electronic reconnaissance. SUBSTANCE: method of modelling of non-uniform geoelectronic media allows to create models of geological sections with non-uniform distribution of longitudinal conductivity and to define the fraction onto them, which is brought by top part of the section into field transient signal. Test models are prepared of conducting media in form of electro-conducting plates with holes. Measurements are conducted by using these plates and value of conductivity depending on diameters of holes to distance between the holes is determined. Then according to results of field measurements the map of conductivities distribution is plotted onto the known area. The map is reproduced in form orbit-nonuniform model, made of electro-conducting plate, provided with groups of holes, any of which corresponds to constant conductivity zone on the map. After that, the model received is subjected to measurements as well. EFFECT: improved precision of modelling. 1 tbl, 1 dwg
