FIELD: the invention refers to geophysics namely to electrical exploration with using of spacing differentiation of the field of formation on several spreads.
SUBSTANCE: the measurements are carried out by several receiving lines. The receiving lines are located in the limits of a sector of 300 from continuation of the feeding lines. Registration of signals of formation of the field is executed either by ground dipole-axle sounding installations with flexible geometry or by maritime sounding installations with uninterrupted registration of signals at moving of the ship. Registered massive of the first and the second differences of potentials are processed. Totality of four interpreted parameters according to which layered values of geoelectrical parameters and distribute them according to the depth are calculated. On their basis conclusion about availability of anomalies connected with hydrocarbon deposits is made.
EFFECT: increases sensitiveness to changing of geoelectrical parameters of the section.
