FIELD: electro-surveying by inductive profiling method, possible use for studying composition of upper part of geological cross-section.
SUBSTANCE: method uses electromagnetic field source and receiving magnetic indicator distanced from one another. Mutual orientation of electromagnetic field source and receiving magnetic indicator is such, that in normal secondary electromagnetic field, excited in radiated geo-electric section without homogeneousness, measured component of magnetic field strength is close to zero. Profiling is performed by means of horizontal displacement relatively to boundary of earth-air splitting simultaneously of source of electromagnetic field and receiving magnetic indicator with discontinuous or continuous registration of abnormal component of magnetic field. On basis of its distribution, presence of geo-electric non-homogeneousness is determined.
EFFECT: increased efficiency and resistance to interference, decreased laboriousness.
