of drill string. It will also discuss troubleshooting of the prob lems that may occur. The IADC definition of a drill string is drillpipe with tool joints attached. Drill stem is all those members between the swivel and the bit, and it includes drill string, kelly or top drive, subs, drill collars, heavy weight drillpipe, stabilizers,
The drill pipe constitutes the majority of the drill string length. It is seamless with threaded connections. The drill pipe has two tool joints, one female is called a box and the other male is called pin. The outer diameter of the tool joint is larger than the body of the drill pipe to accommodate the threads.
A short sub assembly is used to enable the connection of two components with differing thread types or sizes. Float Sub. A float sub has a body which contains a one way check valve to prevent drilling mud and cuttings flowing back up the drill string. Lift Sub. The lift sub is a solid device useful for picking up slick components at the surface.
Drill String Design The following topics will be discussed Kelly Drill pipe Drill collars Accessories; heavy wall drill pipe, jars, stabilizers, reamers, shock sub and bit sub Drill bits 1 . Kelly Used to transmit rotation and weight to bit via drill pipe and drill collars Rotation and weight on bit are essential for breaking rock
sub adaptors The Smoothdrill™ and the Smoothdrive™ line of drilling shock absorbers bring several benefits to any rotary drilling operation. They not only increase penetration rate, but also enable greater drill rig availability. With significant reduction of vibrations transmitted from drill string to drill

Sub drill was incorporated in 1992 and is a proven and trusted manufacturer and supplier of Subsea Tools and Drilling Equipment to the Global Energy Industry.
Drill line (#12) is thick, stranded metal cable threaded through the two blocks (traveling and crown) to raise and lower the drill string. Drill pipe (#16) is a joint of hollow tubing used to connect the surface equipment to the bottom hole assembly (BHA) and acts as a conduit for the drilling fluid. In the diagram, these are stands of drill ...
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 ...
