FIELD: oil and gas industry.
SUBSTANCE: logging device includes housing, centring assembly and scanning head. Housing is oriented along longitudinal axis. Centring assembly positions the housing in the well centre and includes the first slide and group of centring brackets connected to it. The first slide has the possibility of sliding along longitudinal axis so that random control of radial retraction of the above group of centring brackets can be provided. Scanning head rotates scanning sensors axially inside the well around longitudinal axis and includes the second slide and connecting brackets connecting the second slide to the specified scanning sensors. Besides, the second slide has the possibility of sliding along longitudinal axis so that random control of radial retraction of the above sensors can be provided.
EFFECT: increasing the logging efficiency.
