A Rig Move is typically a machine that creates a hole in the earth sub surface, these machines can be used to drill a massive well that includes: Water wells, Natural gas well s, oil wells. Rig in general means an equipment that is used to penetrate through the surface of the earth crust. Mobile rigs are much more efficient that ranges from small to medium sized rigs , that are used in used in mineral exploration drilling, blast-hole, water wells and environmental investigations.
There are different types of rigs available that are capable of switching or combining different drilling technologies as needed
Based On the power used
Efficiently in the field of mechanics rigs are used for uses torque converters, clutches, and transmissions powered by its own engines, often diesel
Machines in general use electric motors with power generated using combustion engines.
The rig primarily uses hydraulic power
The rig is primarily powered by pressurized air
The rig uses steam-powered engines and pumps.
Based On the pipe used
Drill bits can be raised and dropped using a cable.
Makes efficient use of metal or plastic drill pipe of varying types
A giant coil of tube is used for down hole drilling motor
Based On the height
Rigs in general can be differentiated based on height and how many pipe they are able to withstand when there is a need to remove the drill pipe from the hole,
Single: Hold and pulls only single drill pipes, the presence or absence of vertical pipe racking fingers varies from rig to rig.
Double: can hold a stand of pipe which consists of two connected drill pipes, called a “double stand”.
Triple: can hold a stand of pipe which consists of three connected drill pipes, called a “triple stand”.
Quadri: can store stand of pipe that is composed of four connected drill pipes, called a “quadri stand”.
Based On the method of rotation or drilling method
Direct push rigs and most service rigs do not include any rotation.
Rotation is achieved by turning a square or hexagonal pipe at drill floor level using a rotary table.
Drill strings advances vibratory energy using sonic
Rotation and percussive force uses Hammer technique.
Based On the position of derrick
Conventional derrick is vertical.
Slant derrick is slanted at a 45 degree angle to facilitate horizontal drilling.
Drilling rigs includes one of the following:
|Centrifuge: The drilling fluid is separated from silt and sand form in the industries.|
|Solids control: Drilling mud is prepared for the drilling rig using solids control equipments.|
|Chain tongs: Wrench is used to tighten or loosen the section of chain that wraps around which works similar to a pipe wrench.|
|Degasser: Equipment that separates air and gas from the drilling fluid.|
|Desander or desilter: Separates sand and silt from the drilling fluid that contains a set of hydrocyclones.|
|Draw works: It is used to reel in and out the drill line to raise and lower the traveling block that contains a spool from mechanical section.|
|Drill bit: Equipment breaks apart the rock that is attached to the end of the drill, where the drilling fluid exits through the jets.|
|Elevators: a gripping device that is used to latch to the drill pipe or casing to facilitate the lowering or lifting (of pipe or casing) into or out of the borehole.|
|Mud motor: a hydraulically powered device positioned just above the drill bit used to spin the bit independently from the rest of the drill string.|
|Mud pump: reciprocal type of pump used to circulate drilling fluid through the system.|
|Mud tanks: often called mud pits, provides a reserve store of drilling fluid until it is required down the wellbore.|
|Rotary table: rotates the drill string along with the attached tools and bit.|
|Shale shaker: separates drill cuttings from the drilling fluid before it is pumped back down the borehole.|
Rig Moving techniques are used in high consequence industries such as oil and gas, mining, refineries, manufacturing, and construction to reduce the risk, lowers the cost, and improves efficiency and safety.
