Essential Aspects Of Rig Move Classifications And Equipments

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.

Rig Classifications:

There are different types of rigs available that are capable of switching or combining different drilling technologies as needed

Based On the power used

animated-arrow-image-0206 Efficiently in the field of mechanics rigs are used for uses torque converters, clutches, and transmissions powered by its own engines, often diesel

animated-arrow-image-0206 Machines in general use electric motors with power generated using combustion engines.

animated-arrow-image-0206 The rig primarily uses hydraulic power

animated-arrow-image-0206 The rig is primarily powered by pressurized air

animated-arrow-image-0206 The rig uses steam-powered engines and pumps.

Based On the pipe used

animated-arrow-image-0206 Makes efficient use of metal or plastic drill pipe of varying types

animated-arrow-image-0206 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,

animated-arrow-image-0206 Single: Hold and pulls only single drill pipes, the presence or absence of vertical pipe racking fingers varies from rig to rig.

animated-arrow-image-0206 Double: can hold a stand of pipe which consists of two connected drill pipes, called a “double stand”.

animated-arrow-image-0206 Triple: can hold a stand of pipe which consists of three connected drill pipes, called a “triple stand”.

animated-arrow-image-0206 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

animated-arrow-image-0206 Direct push rigs and most service rigs do not include any rotation.

animated-arrow-image-0206 Rotation is achieved by turning a square or hexagonal pipe at drill floor level using a rotary table.

animated-arrow-image-0206 Drill strings advances vibratory energy using sonic

animated-arrow-image-0206 Rotation and percussive force uses Hammer technique.

Based On the position of derrick

animated-arrow-image-0206 Conventional derrick is vertical.

animated-arrow-image-0206 Slant derrick is slanted at a 45 degree angle to facilitate horizontal drilling.

Rig Equipment:

Drilling rigs includes one of the following:

blow out Blowout preventers: (BOPs) These equipments are fixed at the well heads that are dependent on the type of rigs that prevent fluids and gases from escaping the borehole, These offer the same pressure and sealing capacity found in standard pipe rams, while offering the versatility of sealing on various sizes of drill pipe, production tubing and casing without changing standard pipe rams.
centrifuge Centrifuge: The drilling fluid is separated from silt and sand form in the industries.
solid control Solids control: Drilling mud is prepared for the drilling rig using solids control equipments.
chain tongs Chain tongs: Wrench is used to tighten or loosen the section of chain that wraps around which works similar to a pipe wrench.
Vacuum tank degasser Degasser: Equipment that separates air and gas from the drilling fluid.
Desander Desander or desilter: Separates sand and silt from the drilling fluid that contains a set of hydrocyclones.
solid control 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 Drill bit: Equipment breaks apart the rock that is attached to the end of the drill, where the drilling fluid exits through the jets.
Drill pipe Drill pipe: joints of hollow tubing used to connect the surface equipment to the bottom hole assembly (BHA) and acts as a conduit for the drilling fluid. In the diagram, these are “stands” of drill pipe which are 2 or 3 joints of drill pipe connected together and “stood” in the derrick vertically, usually to save time while tripping pipe.
Elevator 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 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 Mud pump: reciprocal type of pump used to circulate drilling fluid through the system.
mud tanks Mud tanks: often called mud pits, provides a reserve store of drilling fluid until it is required down the wellbore.
rotary tables Rotary table: rotates the drill string along with the attached tools and bit.
shale shaker 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.
