The Drill String and Drill Collars

Unlike drill collars, the drill string is not ordinarily used to put weight on the bit. (The drill string is, however, sometimes used to put weight on the bit in horizontal drilling.)

Top Drive Rigs: A Beginner''s Guide to Safer, Faster Drilling

A top drive rig is a piece of equipment used in drilling operations to rotate the drill string (the long pipe that drills into the ground). Unlike older systems that rotate the pipe from

The Essential Guide to Drill Collars: Everything You

By providing the necessary weight and stability to the drill string, drill collars help to maintain the desired rate of penetration, ensure the

Drilling, Rig Types, Drill String Components

To repair or replace parts of the drill string, the crew must hoist or "trip" it out of the hole. During the trip, stands of the pipe are stored between the derrick floor and the monkey board.

The increase in deep and ultra-deep wells demands higher drilling efficiency and more drilling safety. Since the undesired oscillation associated with the tripping in/out of the

Drill string

A drill string on a drilling rig is a column, or string, of drill pipe that transmits drilling fluid (via the mud pumps) and torque (via the kelly drive or top drive) to the drill bit. The term is loosely applied to the assembled collection of the smuggler pool, drill collars, tools and drill bit. The drill string is hollow so that drilling fluid can be pumped down through it and circulated back up the annulus (the void between
