2- RIG TYPES & COMPONENTS



2- LAND RIGS



2- OFF SHORE RIGS

1.Jack - up Rigs. Those rigs drill in water

depths up to 400 ft 1- Provide a fixed platform.

2- does not need a marineriser or subsea stack.



2. SEMI SUBMERSIBLES.1- can work in water up to 2000ft.2- has a god safety records.

Disadvantages:1- need marine risers andsubseastack.2- has limited cargo capacity.

OFF SHORE RIGS (continue)



2. Drilling Ships.1- can work in ultra deep water;more than 2000 ft.2- self propelled.

Disadvantages:1- need marine risers andsubseastack.2- not as stable as jackups andsemisub.




4. Platform Rigs.A rig installed on a fixedmarine plate form.

Can support several rigs.




Land Rig Components

1- Mast or Derrick.

((is the framework-

tower type of support usually

associated with oil

well drilling)).





Land Rig Components

1.1- Monkey Board.

((the platform whichsupport he stands)).

1.1- V-Door.((a triangular openingon the front of thederrick to allow drill

pipes to be pick upfrom the cat walk)).



Land Rig Components

2- Crown.2.1- Crown Sheaves.2.2- Drilling Line.

2.3- Travelling Block.2.4- Hook.



Land Rig Components

3- Elevators.Two elevators are used in

pipe lifting and not usedwhile drilling



Land Rig Components

4- Substructure.This is the support on

which the derrick rest



Land Rig Components

5- Rotary Table.1. Transmits the rotation

to the drill string.2. Suspend the drill stringduring connections & trips



Land Rig Components

Slips These devices are

used to hold the

weight of the drillstring when it is notsupported by the hook(during connections or

tripping time).



Land Rig Components

5- kelly.

This is the topmost joint in the drill

string and is 40-45 feet in length. Itis commonly square or hexagonal.The kelly passes through therotary table and transmits thetable rotation to the drill string viathe kelly bushing.



Land Rig Components

5- Rotary Table.1. Transmits the rotation

to the drill string.2. Suspend the drill stringduring connections & trips



Land Rig Components

5- SWEVEL.

The swivel supports the drill

string and allows rotation atthe same time. It also allowsthe passage of drilling fluidfrom the rotary hose into thedrill string. The swivelperforms a very tough job



Land Rig Components

7- TOP DRIVE.

Replaced kelly and kelly

bushing and it rotates thestring as well1. drilling to be carried outstand by stand instead.2.Top drive is not removedduring trips.



Drilling String Components

This term includes all the components usedto drill below the kelly or top drive; and it caninclude the following components:-1- Drill Pipe & Tool Joints .

2- Heavy weight drill pipe (HWDP.

3- Drill Collars

4- Rotary Bits




3. Stabilizers: of a blade typeconstruction. Drilling fluid can passfreely between the blades while the

outer edge of the blades contacts thewall of the hole and holds the drillcollars firmly centered in the hole.They do exactly as their nameimplies, they provide stability to the bitand collars.




Reamers: These usually have the samediameter as the bit and are run a little distanceabove it

Under-reamers: Used opening out a hole below

a restriction such as imposed by the blow-outpreventer assembly.

Hole Openers: Used for drilling large diameter holes. They have replaceable cutters and serve

the same function as an underreamer exceptthey are not collapsible and can only be usedwhen there is no restriction smaller than the holesize they drill.




Rotary Bits1. Drag Bits:- no movingparts but drill by the

shovelling action of their blade on the formation.2. Roller Bits:- haverotating cones.Three cone bits (Tri-Cone)are the most widely used inthe oil field.






3. Diamond Bits:- Theseare designed to drill by thescraping action of

diamonds set in a steelmatrix. This type of bits isnormally used in hardformations where long bitlife and the subsequent

reduction in trip time are

desirable.



Some Off shore Components

Heave (Motion)Compansation.1- Drill string

compensator.2- Riser & GuidelineTensioners



Mud Pumps

1.Double-acting Pumps (Duplex): - Thismeans that both sides of the piston are used for pumping.

2.Single-acting Pumps (Triplex): - These onlyone side of the piston is used for pumping, thatis, the cylinder is then filling or discharging



1- Shale shaker .2- Desander .3- Desilter .

4- Degaser .5- Mud cleaner .6- Centrifuge.

Solid Control Equipment



Blow Out Preventor (BOP)

a means of closing-off the annular space between the

drill pipe and casing 1- Annular Preventors. 2- Ram Preventors.
