Definition

1. Noun:
   • A series of tubes (joined by screwed collars) that connect a drilling platform to the drilling bit; rotates the bit and supplies drilling mud: A "drilling pipe" is a long, connected assembly of tubular steel sections used in the process of drilling a well. Its primary functions are to transmit rotational force from the surface to the drill bit at the bottom of the hole and to serve as a conduit for circulating drilling fluid (mud) down to the bit and back up to the surface.

Usage Examples

• Noun:
  • The crew is lowering a new section of drilling pipe into the wellbore.
  • Inspection revealed a crack in the drilling pipe, requiring immediate replacement.
  • The weight of the drilling pipe helps apply downward force on the drill bit.

Advanced Usage

• "to run drilling pipe": The process of assembling and lowering the pipe string into the well.

  • The operation was delayed while they ran drilling pipe to the target depth.

• "drilling pipe failure": Refers to a mechanical breakdown, such as a twist-off or burst, in the pipe string.

  • A drilling pipe failure can be a costly and dangerous event.

• Drill pipe (n): A more common, often interchangeable term for "drilling pipe."

  • The drill pipe is manufactured to withstand extreme torque and pressure.

• Drill string (n): A broader term that includes the entire column of drill pipe, drill collars, and other downhole tools.

  • The drill string extends from the rig floor to the bottom of the hole.

Synonyms

• Drill stem: A technical synonym often used in the industry, though it can sometimes refer specifically to the lower, heavier section of the string.

Related Phrases

• "To trip pipe": The process of pulling the drilling pipe out of the hole or running it back in.

  • After reaching total depth, the crew began to trip pipe out of the hole.

• "Stand of pipe": A section of two or three joints of drilling pipe that are connected and handled as a single unit.
