PROTECTIVE ROLLER CENTRALIZER

The invention relates to the field of petroleum engineering and can be used during hydrocarbon production in directional, deviated, horizontal and complex-profile wells. A protective roller centralizer with a cable channel is provided, which comprises: a housing, inside which the cable channel extends longitudinally to the housing along the entire length of the housing; a clamping half-yoke made of at least two parts which are installed in a mirror-like manner and adjacent to each other. The at least two parts are pivotally connected to the housing on one side and are configured to be attached to each other on another side by means of a detachable fastening connection to form an inner cavity for accommodating a tubing pipe. The housing and the clamping half-yoke have ribs formed on their outer surface.
