Write About Everything

Drilling rigs are buildings that house equipment like pipes, cables, drill bits and derricks which are essential in extracting important commodities akin to petroleum from under the earth’s surface. The rigs are categorized under offshore and land with the offshore dealing with drilling on the ocean floor and land based drills dealing with the drilling that’s achieved on land.

Apart from extracting petroleum, they can be used within the building industry in building foundation construction, roadbed, bridges and airports constructions where strong foundations are required. They can be used in mining, drilling and water well drilling. The drilling rigs come in numerous types and probably the most suitable is chosen in keeping with the task that is at hand. The drilling rig classifications may be finished using varied factors, attributes or technologies.

By energy

The kind of energy a drilling rig makes use of can determine what type it is. Usually, yow will discover mechanical drilling rigs which use clutches, transmissions and torque converters which are powered by their own diesel engines. The electric ones are these whose machinery items are driven using electric motors producing power on site via internal combustion engines. There are also hydraulic rigs which use hydraulic power, steam rigs which use engines and pumps that are steam powered and the pneumatic ones which are powered using pressurized air.

By Pipe

Rig categorization under pipe has cable drilling rigs that use cables to lift and drop drill bits, standard drilling rigs which use plastic or metal drill pipes of various types to suit the perform and col tubing rigs that use giant tube coils and down gap drilling motors.

By height

Height categorization comes in when quickly removing drill pipes from the opening and relies on the number of related pipes within the derrick. Single rigs pull dingle drill pipes, whereas double rigs can deal with a stand of pipe that has connected pipes in the derrick. Triple stand rigs can deal with three whereas quadri stand can accommodate four linked drill pipes.

By drilling methodology

The drilling technology classifies the drilling rigs into non rotational rigs that embrace most service rigs and direct push rigs. There are also rotary table rigs that achieve rotation by turning a hexagonal or square pipe on the floor level of the drill. Top drive rigs have the circulation and rotation performed across the top area of drill string on motors moving on track along the equipment derrick whereas sonic rigs use vibratory energy so that the drill string is advanced. You will additionally find hammer rigs that use percussive and rotation force.

By derrick position

Drilling rigs can be categorized in response to the positioning of the derrick on the equipment. There are conventional rigs that have the derrick in vertical position and slant rigs which have the derrick slanted at an angle of 25 degrees so that horizontal drilling is facilitated.

Whatever the drilling needs you have got, there may be always an significance of making positive you select one of the best for the task at hand. Once you know what your options are your possibilities of choosing one of the best drilling rig are increased.
