DOWNHOLE PRESSURE INTENSIFIER FOR JET CUTTING |
摘要 |
The present invention provides a drilling system that utilizes the drilling fluid in a borehole to drive an apparatus to generate a high-pressure jet of fluid to facilitate the drilling operation. A pressure intensifier disposed between a drilling motor and the drill bit generates high pressure fluid jet. The drilling motor rotates the pressure intensifier. Fluid enters a high pressure chamber in the pressure intensifier at selected location during each rotation. A piston in the pressure intensifier discharges the fluid from the high pressure chamber to the drill bit bottom at a high pressure. An electrically-operated pulse frequency control device generates fluid pulses of at least two frequencies, each such frequency defining a bit of a binary system. |
