The Completely different Types Of Drilling Rigs
Drilling rigs are structures that house equipment like pipes, cables, drill bits and derricks which are mandatory in extracting vital commodities comparable to petroleum from underneath the earth’s surface. The rigs are categorized below offshore and land with the offshore handling Borehole drilling Limpopo on the ocean flooring and land primarily based drills dealing with the drilling that’s executed on land.
Aside from extracting petroleum, they can be used within the construction business in building foundation building, roadbed, bridges and airports constructions the place strong foundations are required. They can be utilized in mining, drilling and water well drilling. The drilling rigs come in numerous types and the most suitable is selected in response to the duty that is at hand. The drilling rig classifications can be performed utilizing numerous factors, attributes or technologies.
The type of power a drilling rig uses can decide what type it is. Normally, you could find mechanical drilling rigs which use clutches, transmissions and torque converters which are powered by their very own diesel engines. The electrical ones are those whose machinery gadgets are pushed utilizing electrical motors generating energy on site via inside combustion engines. There are also hydraulic rigs which use hydraulic power, steam rigs which use engines and pumps that are steam powered and the pneumatic ones which are powered utilizing pressurized air.
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 function and col tubing rigs that use large tube coils and down gap drilling motors.
Height categorization is available in when quickly removing drill pipes from the opening and is predicated 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 connected pipes in the derrick. Triple stand rigs can deal with three whereas quadri stand can accommodate four connected drill pipes.
By drilling technique
The drilling expertise 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 at the floor level of the drill. Prime drive rigs have the circulation and rotation finished around the prime space of drill string on motors moving on track along the gear derrick whereas sonic rigs use vibratory energy so that the drill string is advanced. Additionally, you will discover hammer rigs that use percussive and rotation force.
By derrick position
Drilling rigs may also be categorized based on the positioning of the derrick on the equipment. There are conventional rigs that have the derrick in vertical place and slant rigs which have the derrick slanted at an angle of 25 degrees so that horizontal drilling is facilitated.
