Abstract: Slow-rotating tools may operate within a tubular structure such as casing or tubing strings in a wellbore, e.g., to clean an interior surface of the tubular structure or to support other wellbore applications. A slow-rotating tool may include a nozzle assembly that rotates with respect to an end of a coiled tubing strand or other conveyance, and a working fluid delivered through the conveyance may operate to drive rotation of the nozzle assembly. A motor component of the tool may include a coiled conduit that winds and un-winds in response to pressure fluctuations in the working fluid. The coiled conduit may be operably coupled to a pair of directional clutches that harness the rotational motion induced by the winding and unwinding, and impart the rotational motion to the rotatable housing in a single direction.
