Drilling rigs are buildings that house equipment like pipes, cables, drill bits and derricks which are needed in extracting necessary commodities equivalent 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 based drills handling the drilling that is done on land.
Apart from extracting petroleum, they can be used within the construction trade in building basis development, roadbed, bridges and airports constructions the place robust foundations are required. They may also be utilized in mining, drilling and water well drilling. The drilling rigs come in several types and essentially the most suitable is selected in line with the task that is at hand. The drilling rig classifications will be executed utilizing varied factors, attributes or technologies.
The kind of power a drilling rig uses can determine what type it is. Generally, you will discover 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 by inner combustion engines. There are also hydraulic rigs which use hydraulic energy, steam rigs which use engines and pumps which are steam powered and the pneumatic ones which are powered using pressurized air.
Rig categorization under pipe has cable drilling rigs that use cables to boost and drop drill bits, typical drilling rigs which use plastic or metal drill pipes of different types to suit the perform and col tubing rigs that use giant tube coils and down gap drilling motors.
Height categorization comes in when temporarily removing drill pipes from the opening and relies on the number of linked 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 handle three whereas quadri stand can accommodate four 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 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 done around the top area 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 find hammer rigs that use percussive and rotation force.
By derrick position
Drilling rigs may 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 that have the derrick slanted at an angle of 25 degrees so that horizontal drilling is facilitated.
Regardless of the drilling wants you’ve, there may be always an importance of making certain you select the very best for the task at hand. Once you know what your options are your probabilities of choosing the best drilling rig are increased.
