The utility model discloses a radial jet motor aggravates device. Radial jet motor aggravates device, including aggravating a body (1), the upside that aggravates the upper end of a body (1) is provided with and connects upper end box (2), and the downside of upper end is provided with and connects lower extreme pin thread (3), it is used for being connected with coiled tubing (4) to connect upper end box (2), it is used for being connected with the motor of windowing (5) to connect lower extreme pin thread (3), increase the weight of still to be provided with on the outer wall of a body (1) a plurality of gyro wheel (6), the rotation axis of gyro wheel (6) with the axis that aggravates a body (1) is perpendicular. The utility model discloses the sliding friction that will increase the weight of a body and the wall of a well, pipe wall has been transformed into rolling friction, the effectual frictional resistance that has reduced makes on the gravity that increases the weight of a section of thick bamboo can effectually transmit the drill bit, has solved the technical problem that the weight on bit is not enough when highly deviated well radial jet creeps into the operation, has improved success rate and efficiency that radial jet crept into the technology.
