摘要： A drilling assembly for drilling pipe into a drilling surface using a drill bit. The drilling assembly comprises a power unit, a thrust frame, a means for moving the thrust frame, a rotary and carriage assembly and a microprocessor adapted to control the load on the drill based upon the level of mud pressure in the assembly. The drilling assembly is adapted to drill pipe at any angle relative to the drilling surface between substantially parallel to the drilling surface and substantially perpendicular to the drilling surface. The method comprises providing a such drilling assembly, placing a drill pipe onto the drilling assembly, moving the thrust frame to a desired drilling angle, moving the rotary and carriage assembly into direct contact with the drill pipe, applying rotational, thrust and pull-back forces to the drill pipe, drilling the pipe into the drilling surface and controlling the load on the drill bit.
