drilling tools
supply you with the most common types of drills used in the oil and gas field
Drill bits
Roller cone bits are the most common type of drill bit used in oil and gas drilling. They have a rotating cone with rows of teeth that chip away at the rock. Roller cone bits are available in a variety of sizes, from 3 7/8″ to 36″.
Drill collars:
Drill collars are thick-walled tubular pieces that are used at the bottom of the drill string in oil and gas drilling. They provide the axial force needed to advance the drill bit, and they also help to dampen the vibrations and impact forces caused by drilling.
Drill pipe
Drill pipe is a hollow, thin-walled, steel or aluminum alloy piping that is used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annulus. It comes in a variety of sizes, strengths, and wall thicknesses, but is typically 27 to 32 feet in length (Range 2). Longer lengths, up to 45 feet, exist (Range 3).
