There are two types of Rotating Systems:

Swivel and Swivel Bail

The Kelly

Kelly Bushing

Rotary table

Master bushing

rigs this may be replaced

by a top drive)

Components of the Kelly System:

SwivelHangs below the traveling block and

supports the drill stem system.

The swivel does not rotate but it (allows)

the equipment below it to rotate.

Swivel BailA curved steel rod on top of the swivel

that resembles the handle.

The KellyIt is a special section of pipe that

is attached to the bottom of the

swivel by threading.

They comes in 40ft and 54ft

lengths.

The Kelly is not round, It has a

hexagonal (6 sides) or square

shape. (4 sides).

Kelly Bushing and Master Bushing.

The Kelly fit into a device called

"The Kelly bushing.

The "Kelly bushing" then fits into

"The Master bushing" which is

mounted on the rotary table.

The Rotary Table.The rotary table is the

primary component in the

rotating system.

It is used in both the Kelly

system and Top Drive

system.

The rotary table is located

on the floor of the rig and it

is capable of producing astrong rotating force called

"TORQUE".

Additional equipment

transmits torque from the

rotary table to the bit.

Components of the Kelly System:

The Slips.It is a gripping

device used to hold

up the drill string

during connections

process.

Kelly Bushing and Master Bushing.A powered gear located inside the rotary table turns the master bushing.

The master bushing turns the Kelly bushing.

The square or hexagonal opening in the Kelly Bushing fits against the flat

sides of the Kelly itself and causes it to spin.

This system of operation is similar to a wrench turning the head of a bolt.

The drill stem and bit are turned by the Kelly.

The Kelly slides up and down freely inside the opening in the Kelly

Bushing allowing it to move down as the bit drills into the hole.

Components of the Kelly System:

NOTE: 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 .

Top Drive System

8/2/2019 Kelly Down Sistem

10/18

Top Drive System

The Top Drive System

hangs below the traveling

block and has its own heavy

duty motor.

It is comprised of one ormore electric or hydraulic

motors

These are connected to the

drill string by a short section

of pipe called the Quill

The top drive is able to

move up and down the

derrick

Top Drive System

The Top Drive System does not

use a Kelly, Kelly Bushing, or

master Bushing

It does utilize the Rotary Table

The Rotary Table is primarily

used as a place for thee crew tohold the drill stem in place

Top Drive System

A top drive is able to drill with three joints stands

Decreases the frequency of pipe getting stuck

Allows drillers to quickly engage and disengage pumps while removing

or restringing the pipe

Top drives are preferable for use in challenging extended-reach and

directional wells

Top drives remove much of the manual labor involved with drilling

The top drive is completely automated

Top drives can be used in all types of environments

Drill Pipe

Drill pipe: Drill Pipe forms the upper

part of the drill string. Each section of

pipe is called a joint with a box

(female) and pin (male) located on the

ends.

Drill pipe is threaded together or

assembled in sections and put into the

hole as the bit turns.

Drill pipe is hollow and allows fluid

or transmitting wires to pass through.

Drill Pipe

Spindle Adapter: Called a saver sub

which threads into the rotary head and

drill pipe.

Transition pipe: is used as a transition

between the limber drill pipe and the

collars.

Drill Collars: A pipe with thick walls

that are attached to the bottom of thedrill string. They add weight to the bit

and make the bit's cutter's bite into the

rock. Normally multiple drill collars are

used to add weight.

Drill Pipe

Crossover subs: A crossover sub

is used between the drill string and

drill collars.

Manufacturers design these to

join parts of the drill string that

have different thread designs.

The Drill Bit

Drill Bit: It is Located at the bottom end of the drill string and make contact

with the subsurface layers, and drilling through them.
