FIELD: measuring equipment.
SUBSTANCE: invention belongs to logging measurements. Substance: the device (100) for logging measurement of microresistance includes a monopolar injecting current electrode (160) and at least the first and second pairs of measuring electrodes (212, 214; 226, 228). The device (100) can additionally include a control unit, configuration of which allows to carry out measurements of microresistance of the anisotropic medium by means of the single discharge from the monopolar injecting current electrode (160). The control unit can have a configuration, allowing to calculate a two-dimensional tensor of specific resistance of a local layer on the basis of application of the single discharge from a monopolar injecting current electrode (160).
EFFECT: application of a single discharge promotes reduction of duration of measurement that, in turn, promotes increase of azimuthal sensitivity in drawing up of a map of microresistance of anisotropic medium in the course of drilling.
