FIELD: geophysics.
SUBSTANCE: the invention relates to geophysics and is used for to carry out complex geophysical inspection of oil and gas wells, operated with a horizontal bore. The complex device for well inspection can be descended into the well bore by means of logging cable. The device comprises a cylindrical casing fitted with level stabilizer which centers the device along the well axis. The stabilizer has at least six levers. Each level has at least one fluid flow temperature sensor, at least one influx thermal indicator and at least one fluid composition sensor which are distributed along the perimeter of the well bore in one line parallel to the device axis. The casing is fitted with additional upper lever stabilizer in the tail-end of the device.
EFFECT: increased information content, increased device efficiency, expanded capacities in foliated multi-phase flow.
