Drilling rigs are constructions that house equipment like pipes, cables, drill bits and derricks which are crucial in extracting vital commodities such as petroleum from under the earth’s surface. The rigs are categorized under offshore and land with the offshore handling drilling on the ocean floor and land based drills handling the drilling that is performed on land.

Apart from extracting petroleum, they can be used in the construction business in building basis construction, roadbed, bridges and airports constructions where robust foundations are required. They can also be utilized in mining, drilling and water well drilling. The drilling rigs come in several types and the most suitable is selected in accordance with the task that’s at hand. The drilling rig classifications will be performed using numerous factors, attributes or technologies.

By energy

The kind of energy a drilling rig uses can determine what type it is. On the whole, you’ll find mechanical drilling rigs which use clutches, transmissions and torque converters that are powered by their own diesel engines. The electric ones are these whose machinery items are pushed utilizing electric motors producing power on site through inner combustion engines. There are additionally hydraulic rigs which use hydraulic energy, steam rigs which use engines and pumps which can be steam powered and the pneumatic ones which are powered utilizing 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 operate and col tubing rigs that use large 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 related pipes in the derrick. Triple stand rigs can handle three whereas quadri stand can accommodate 4 related drill pipes.

By drilling method

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 square pipe on the floor level of the drill. Top drive rigs have the circulation and rotation done around the top area of drill string on motors moving on track along the equipment derrick whereas sonic rigs use vibratory energy in order that the drill string is advanced. You will additionally discover hammer rigs that use percussive and rotation force.

By derrick position

Drilling rigs will also be categorized in line with the positioning of the derrick on the equipment. There are typical rigs which 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.

Regardless of the drilling needs you have got, there is always an significance of making positive you select the best for the task at hand. Whenever you know what your options are your possibilities of selecting the most effective drilling rig are increased.
