Drilling rigs are constructions that house equipment like pipes, cables, drill bits and derricks which are vital in extracting important commodities similar 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 mostly drills dealing with the drilling that is done on land.

Apart from extracting petroleum, they can be utilized in the construction industry in building foundation development, roadbed, bridges and airports constructions where sturdy foundations are required. They can also be used in mining, drilling and water well drilling. The drilling rigs come in several types and essentially the most suitable is chosen in accordance with the task that’s at hand. The drilling rig classifications could be accomplished using various factors, attributes or technologies.

By power

The kind of power a drilling rig uses can decide what type it is. Basically, yow will discover mechanical drilling rigs which use clutches, transmissions and torque converters which might be powered by their own diesel engines. The electric ones are those whose machinery items are pushed utilizing electric motors generating energy on site via inside combustion engines. There are also 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 boost and drop drill bits, standard drilling rigs which use plastic or metal drill pipes of different 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 briefly removing drill pipes from the hole and relies on the number of linked pipes within the derrick. Single rigs pull dingle drill pipes, whereas double rigs can handle a stand of pipe that has two linked pipes in the derrick. Triple stand rigs can deal with three whereas quadri stand can accommodate 4 related drill pipes.

By drilling technique

The drilling technology classifies the drilling rigs into non rotational rigs that embody most service rigs and direct push rigs. There are additionally rotary table rigs that achieve rotation by turning a hexagonal or sq. pipe on the floor level of the drill. High drive rigs have the circulation and rotation achieved across the top space of drill string on motors moving on track alongside the equipment derrick whereas sonic rigs use vibratory energy in order 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 that 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 importance of making sure you choose the most effective for the task at hand. If you know what your options are your possibilities of choosing the very best drilling rig are increased.
