The utility model relates to an internal conducting impeller-type nozzle for a continuous tube, which mainly used for the sand washing, the descaling and the washing of oil wells. The nozzle is formed from orderly connecting a nozzle body, a rotating body, a nozzle carrier and a nozzle, wherein steps are arranged in the cavity on the lower portion of the nozzle body, the rotating body is installed on the steps, and the steps stop the top of the rotating body, and the top of nozzle carrier stops the bottom of the rotating body, sealing threads of the nozzle carrier are connected on the bottom of the nozzle body, and the nozzle is installed at an opening on the bottom of the nozzle carrier. The exterior of the rotating body is in a columnar shape, and the center of a column is a spindle water division head whose both ends are pointed, a chute is arranged on the column body, and the chute is in a spiral shape, the inner wall of the nozzle carrier is in a conical contracted shape. Fluid enters the chute of the rotating body through the nozzle body and the rotation thereof is strengthened, forms a spiral conical jet flow, and is jetted from the nozzle. The utility model has the advantages of simple structure, small size and light weight, and the jet flow generates the shear fragmentation, the erosion fragmentation and the rotational flow grinding to sand beds and improves the jet flow efficiency.
