Write About Everything

Drilling rigs are constructions that house equipment like pipes, cables, drill bits and derricks which are obligatory in extracting necessary commodities akin to 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 primarily based drills handling the drilling that’s carried out on land.

Apart from extracting petroleum, they can be used within the development trade in building foundation building, roadbed, bridges and airports constructions the place strong foundations are required. They can also be used in mining, drilling and water well drilling. The drilling rigs come in several types and the most suitable is selected in line with the task that’s at hand. The drilling rig classifications may be performed using various factors, attributes or technologies.

By power

The kind of power a drilling rig makes use of can determine what type it is. In general, you’ll find mechanical drilling rigs which use clutches, transmissions and torque converters which can be powered by their own diesel engines. The electric ones are these whose machinery items are driven using electric motors producing energy on site via internal 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 using pressurized air.

By Pipe

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

By height

Height categorization is available in when briefly removing drill pipes from the outlet and is predicated on the number of linked pipes in the derrick. Single rigs pull dingle drill pipes, whereas double rigs can deal with a stand of pipe that has connected pipes within the derrick. Triple stand rigs can deal with three whereas quadri stand can accommodate four linked 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 also rotary table rigs that achieve rotation by turning a hexagonal or sq. pipe at the floor level of the drill. High drive rigs have the circulation and rotation achieved around the top space 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 discover hammer rigs that use percussive and rotation force.

By derrick position

Drilling rigs may also be categorized according to the positioning of the derrick on the equipment. There are conventional 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.

Whatever the drilling wants you have got, there may be always an importance of making certain you choose the perfect for the task at hand. While you know what your options are your chances of choosing the very best drilling rig are increased.
