The Different Types Of Drilling Rigs
Drilling rigs are structures that house equipment like pipes, cables, drill bits and derricks which are necessary in extracting necessary commodities comparable 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 primarily based drills dealing with the drilling that is completed on land.
Apart from extracting petroleum, they can be used in the construction business in building basis construction, roadbed, bridges and airports constructions the place sturdy foundations are required. They can be utilized in mining, drilling and water well drilling. The drilling rigs come in different types and probably the most suitable is chosen in keeping with the task that's at hand. The drilling rig classifications could be done using varied factors, attributes or technologies.
The kind of power a drilling rig makes use of can decide what type it is. On the whole, you can find mechanical drilling rigs which use clutches, transmissions and torque converters which can be powered by their own diesel engines. The electric ones are those whose machinery items are pushed utilizing electric motors generating power on site via inner combustion engines. There are also hydraulic rigs which use hydraulic energy, steam rigs which use engines and pumps which might be steam powered and the pneumatic ones which are powered using pressurized air.
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 different types to suit the perform and col tubing rigs that use big tube coils and down gap drilling motors.
Height categorization comes in when quickly removing drill pipes from the opening and is predicated on the number of connected pipes in the derrick. Single rigs pull dingle drill pipes, whereas double rigs can handle a stand of pipe that has two connected pipes within the derrick. Triple stand rigs can handle three whereas quadri stand can accommodate 4 connected drill pipes.
By drilling methodology
The drilling technology classifies the drilling rigs into non rotational rigs that include most service rigs and direct push rigs. There are additionally rotary table rigs that achieve rotation by turning a hexagonal or square pipe at the floor level of the drill. Prime drive rigs have the circulation and rotation executed 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 also discover hammer rigs that use percussive and rotation force.
By derrick position
Drilling rigs can also be categorized in accordance with the positioning of the derrick on the equipment. There are standard rigs which 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 will have, there is always an importance of making sure you choose the most effective for the task at hand. If you know what your options are your probabilities of selecting the very best drilling rig are increased.
