High-pressure jet-flow radial level drilling well system

The utility model provides a high pressure water jet radial horizontal drilling system, which relates to a single-purpose down-hole tool for a horizontal drilling process and a best combination of the single-purpose down-hole tool, wherein drilling rods are rotated in an ultra-short radius and rocks are broken by completely high pressure water jet in the horizontal drilling process. The utility model solves a ultra-short radius horizontal drill problem, and the technical project of the utility model is that a wellhead sealed tool (11), a wellhead three-way valve (12), a anchor (13), an orientation link (14) and a diverter (2) are connected with a working pipe column (15) in series to form a outer pipe assembly (I), a drill bit (3), a drilling rod (4), a pumping rod (5), a feeding polish rod (7) form a inner pipe assembly (II), the upper section of the diverter arranged on the lower portion of the outer pipe assembly (I) show multiple-layer tubular shaped, a rotary drum assembly (214) arranged on the lower section of the diverter can form a vertical drilling horizontal drilling rod channel, high pressure drilling fluid (8) drives the drilling rod (4) and the drill bit (3) to thread the drilling rod channel and penetrate into ground layer, at the same time, the high pressure drilling fluid (8) is ejected with high revolution rate via the drill bit (3) to break the rocks of the ground layer, thereby forming radial horizontal borehole (V). The utility model can be used for increasing yield in oil field.
