摘要： A drill pipe (10) is disclosed which includes a cylindrical pipe section (12), a box end (14), a pin end (16) and a hydraulic hose assembly (18) connected between the box and pin ends and extending within the cylindrical pipe section. By passing drilling fluid through the hydraulic hose assembly (18), the interior surface of the cylindrical pipe section (12) is not exposed to the drilling fluid and does not need to be treated to prevent corrosion. Further, the reduced volume of the hydraulic hose assembly (18) relative to conveying the drilling fluid through the interior of the cylindrical pipe section reduces significantly the waste of drilling fluid, allows the fluid to be pressurized more rapidly to initiate drilling operation, and limits fluid spill damage to the environment. A rigid or flexible tube can replace the hose assembly (18), with the tube attached to the ends by threads, seals, press fits, O-rings or adhesives, or any combination thereof.
