| Abstract: | The wedge is a means and method for directional drilling technique, its main process is hole-bottom bridging and hard rock ground drilling technique by means of wedge. With the combination of construction and scientific research, improvement was made on the hydraulic type hole-bottom metal plug and diamond bit. Through the construction for years and compared the application effects of 3 boreholes, good results were obtained. |
