The invention discloses a self-control shooting distance water jet drill, relates to a high pressure water jet drill, and solves the problems of uncontrollable shooting distance, low pore-forming rate of drilling and sticking of tool existing in the conventional water jet drill. The self-control shooting distance water jet drill is characterized in that: a spray nozzle is a cylindrical cavity of which the upper end is provided with water jet holes; a hollow drilling core is in sliding fit with an inner chamber of a shell; the upper end of the hollow drilling core is provided with a limit nut, and the lower end of the hollow drilling core is provided with a liquid inlet pipe joint; the hollow drilling core is provided with a main flow guide passage, an upper transverse deflector hole and a lower transverse deflector hole along an axis; the upper transverse deflector hole and the lower transverse deflector hole are symmetrical about each other up and down along the axis; and the upper part of the shell is provided with an upper diversion trench which is communicated with the spray nozzle, and the lower end of the shell is provided with a lower diversion trench which is communicated with the bottom end of the drill. By using the self-control shooting distance water jet drill, the jet shooting distance can be controlled, so a water jet technique can be further popularized in the field of drilling.
