Drilling rigs are buildings that house equipment like pipes, cables, drill bits and derricks which are needed in extracting essential 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 primarily based drills handling the drilling that’s accomplished on land.
Apart from extracting petroleum, they can be used within the development business in building basis building, 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 numerous types and the most suitable is chosen based on the task that is at hand. The drilling rig classifications could be completed using numerous factors, attributes or technologies.
The kind of energy a drilling rig makes use of can decide what type it is. Typically, you 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 using electric motors generating energy on site by means of inside combustion engines. There are additionally hydraulic rigs which use hydraulic energy, 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 lift and drop drill bits, typical drilling rigs which use plastic or metal drill pipes of different types to suit the operate and col tubing rigs that use big tube coils and down hole drilling motors.
Height categorization is available in when temporarily removing drill pipes from the hole and is based on the number of connected pipes within the derrick. Single rigs pull dingle drill pipes, whereas double rigs can deal with a stand of pipe that has related pipes within the derrick. Triple stand rigs can handle three whereas quadri stand can accommodate 4 related 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 also rotary table rigs that achieve rotation by turning a hexagonal or square pipe on the floor level of the drill. High drive rigs have the circulation and rotation carried out around the top area of drill string on motors moving on track alongside the equipment derrick whereas sonic rigs use vibratory energy so that the drill string is advanced. You will also find hammer rigs that use percussive and rotation force.
By derrick position
Drilling rigs will also be categorized in response to the positioning of the derrick on the equipment. There are typical rigs that 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 needs you have got, there’s always an importance of making positive you select the very best for the task at hand. Once you know what your options are your chances of choosing the very best drilling rig are increased.
