description The invention relates to a continuous-shocking-type horizontal well drill feeding tool used for horizontal well drilling in the petroleum and nature gas industry. According to the continuous-shocking-type horizontal well drill feeding tool, the problems that horizontal well drill columns are difficult to feed and pressure releasing occurs to drill bits are solved. According to the technical scheme, the upper end of an upper tube body is in screwed connection with the upper drill column, and the lower end of a lower connector is in screwed connection with the lower drill column; the lower end of a spiral rotor is in screwed connection with the upper end of a center pipe, and a thrust bearing is mounted on a protruded step on the outer circle of the lower end of the spiral rotor; a circle ofprotruded step is arranged on the upper portion of an inner cavity of a connecting tube, and a spring a is mounted on a protruded step on the upper portion of the inner cavity of the connecting tube;the upper end of the conn
