The Totally different Types Of Drilling Rigs

Drilling rigs are buildings that house equipment like pipes, cables, drill bits and derricks which are vital in extracting necessary commodities reminiscent of 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 is finished on land.

Apart from extracting petroleum, they can be utilized within the development industry in building foundation building, roadbed, bridges and airports constructions where sturdy foundations are required. They may also be utilized in mining, drilling and water well drilling. The drilling rigs come in different types and the most suitable is selected in response to the task that’s at hand. The drilling rig classifications will be done using numerous factors, attributes or technologies.

By energy

The kind of power a drilling rig uses can determine what type it is. Usually, you can find mechanical drilling rigs which use clutches, transmissions and torque converters which might be powered by their own diesel engines. The electric ones are these whose machinery items are driven using electric motors generating energy on site through inside combustion engines. There are additionally hydraulic rigs which use hydraulic energy, steam rigs which use engines and pumps which 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 raise and drop drill bits, typical drilling rigs which use plastic or metal drill pipes of different types to suit the perform and col tubing rigs that use big tube coils and down gap drilling motors.

By height

Height categorization comes in when quickly removing drill pipes from the outlet and is predicated on the number of connected pipes within the derrick. Single rigs pull dingle drill pipes, whereas double rigs can handle a stand of pipe that has connected pipes within the derrick. Triple stand rigs can deal with three whereas quadri stand can accommodate 4 linked drill pipes.

By drilling method

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

By derrick position

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

Whatever the drilling wants you have got, there’s always an significance of making sure you select the best for the task at hand. Whenever you know what your options are your chances of selecting the most effective drilling rig are increased.
