发明名称 METHOD AND APPARATUS FOR LATERAL DRILLING THROUGH A SUBTERRANEAN FORMATION
摘要 An internally rotating nozzle for facilitating drilling through a subterranean formation is rotatably mounted internally within a housing connected to a hose for receiving high pressure fluid. The rotor includes at least two tangential jets oriented off of center for ejecting fluid to generate torque and rotate the rotor and cut a substantially cylindrical tunnel in the subterranean formation.
