Cable tool drilling tools

There are five main tools used

in cable tool drilling rig. Which are given below,

1: Drill line or cable.

2: Swivel Socket.

3: Drilling Jars.

4: Drill Stem.

5: Drill Bet.

1: Drill line or cable:

A wire rope hoisting line, rived on sheaves of the

crown block and traveling block (in effect a block and tackle).

Its primary purpose is to hoist or lower drill pipe

or casing from or into a well. Also, a wire rope used

to support the drilling tools.

2: Swivel socket:

A Swivel is a mechanical device used on a drilling rig

that hangs directly under the traveling block and

directly above the Kelly drive, that provides the ability for

the Kelly (and subsequently the drill string) to rotate while

allowing the traveling block to remain in a stationary rotational position

3: Drilling Jars:

A jar is a tool that sits on the drill string. If the drill-string

(BHA) gets stuck in the hole, the jar can help knock

it loose by generating quick, sharp hammer-like blows.

4: Drill Stem:

A Drill Stem, also known as a drill string is a string

or a column of a drill pipe present on a rig which is

used to transmit torque and drilling fluids to the drill

bit. ... It is a combination of the bottom hole assembly,

drill pipe and other tools that are used to make drill

bits turn at the bottom of the well-bore.

5: Drill Bit:

Drill Bit is a cutting tool . Which is used in petroleum industries

for cutting. A drilling bit is used in petroleum exploration

to drill a well-bore through various layers of rock formations

to access oil or natural gas resources. It is engineered

to penetrate the subsurface rock formations and to do

so quickly and for as long as possible.
