Drill pipe - seamless products of an annular section, obtained by rolling. Steel drill pipe 63.5x5mm L=1200mm - an integral part of the drill string, provides mechanical and hydraulic connection between the cutting tool (bit) working at the bottom and surface drilling equipment.
Pipes are used for:
- transportation of the rock cutting tool along the well;
- formation of the desired rotation and torque with simultaneous transfer of axial load;
- lifting of working tools from the bottom of the well to the surface;
- for supplying drilling fluid, which performs the function of cooling the cutting element;
- for supplying flushing fluid to clean the wellbore from cuttings;
- creation of hydraulic energy when using downhole motors.
Pipes for drilling are part of the drilling rigs.
The pipes are connected to each other using upset locks with a large locking thread, which has a significant taper.
Such a thread allows screwing-breaking out in a few turns, and the intense contact of the end surfaces ensures the tightness of the joints.
In places of landing, the pipes are thickened with internal or external landings, which increases their strength.
Drill pipes are characterized by low fatigue strength for alternating loads, which ensures their long and trouble-free operation.
