Different types of Different types of Drilling Rigs

Drilling rigs are structures that house equipment like pipes, cables, drill bits and derricks which are necessary in extracting important commodities such as 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 based drills handling the drilling that is completed on land.

Other than extracting petroleum, they can be used in the development industry in building foundation construction, roadbed, bridges and airports constructions where strong foundations are required. They can be used in mining, drilling and water well drilling. The drilling rigs are available different types and the best suited is selected according to the task that is at hand. The drilling rig classifications will be done using various factors, attributes or technologies.

By power
The sort of power a drilling rig uses can determine what type it’s. Typically, you will discover mechanical drilling rigs which use clutches, transmissions and torque converters which are powered by their very own diesel engines. The electric ones are those whose machinery items are driven using electric motors generating power on site through internal 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 that are powered using pressurized air.

By Pipe
Rig categorization under pipe has cable drilling rigs that use cables to lift and drop drill bits, conventional drilling rigs which use plastic or metal drill pipes of differing kinds to suit the function and col tubing rigs that use giant tube coils and down hole drilling motors.

By height
Height categorization is available in when temporarily removing drill pipes from the outlet and relies on the variety 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 four connected drill pipes.

By drilling method
The drilling technology classifies the drilling rigs into non rotational rigs that include most service rigs and direct push rigs. crude oil well crude oil well There are also rotary table rigs that achieve rotation by turning a hexagonal or square pipe on the floor level of the drill. Top drive rigs have the circulation and rotation done around the top area 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. Additionally, you will find hammer rigs that use percussive and rotation force.

By derrick position
Drilling rigs can also be categorized in keeping with the positioning of the derrick on the equipment. There are conventional 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 may have, there’s always an importance of making sure you choose one of the best for the duty at hand. When you recognize what your options are your chances of choosing the best drilling rig are increased.
