What is substructure in drilling rig?

Substructures are the structural components of land and water-based oil platforms which support the derrick, mast, or other rig components, as well as providing storage space below the main deck.

What are the four main types of drill rigs?

Depending on the terrain, you can choose between different types of drilling rigs: rotary drilling rigs, percussion drilling rigs, down-the-hole drilling rigs, top hammer drilling rigs (with high hammer), etc.

• Dowel Bits.

What is mast in drilling?

A drilling mast is a structure over an oil well which supports the drilling equipment and allows it to be lifted into and out of the wellbore. The crown block is supported by the top platform of the drilling mast or derrick. A drilling mast or derrick was erected over the well.

What are the components of substructure?

• Plinth Beam.

How many types of drilling rigs are there?

Offshore drilling are divided into two types: Fixed structure types and Floating structure types. Jack-up Rig.

What is a jack-up drilling rig?

Jack-up rigs are mobile, self-elevating drilling and workover platforms equipped with legs that can be lowered to the ocean floor until a foundation is established to support the hull, which contains the drilling and/or workover equipment, jacking system, crew quarters, loading and unloading facilities, storage areas …

What is drilling and its types?

What is difference between derrick and mast?

is that derrick is a device that is used for lifting and moving large objects while mast is a tall, slim post or tower, usually tapering upward, used to support, for example, the sails on a ship, flags, floodlights, or communications equipment such as an aerial, usually supported by guy-wires or mast can be the fruit …

What is crown block in drilling?

A crown block is the stationary section of a block and tackle that contains a set of pulleys or sheaves through which the drill line (wire rope) is threaded or reeved and is opposite and above the traveling block.

What are the different types of drilling rigs?

There are many different types of drilling rigs. Which rig selected depends on the specific requirments of each drill site. Rigs are generally categorized as onshore (land) or offshore (marine). Onshore rigs are all similar, and many modrn rigs are of the cantilevered mast, or “Jackknife” derrick type.

How are slingshot substructures used on a drilling rig?

Slingshot substructures are self-elevating. The drill floor and platform allow a cantilevered mast to be installed at ground floor. The mast and substructure raise into working position and hydraulic cylinders at the sides of the mast act as bumpers. This substructure is acceptable for electrical rigs.

What are the substructures of an oil rig?

Substructures are the structural components of land and water-based oil platforms which support the derrick, mast, or other rig components, as well as providing storage space below the main deck. They are customized according to an application’s needs, but there are several classifications for substructures.

How does a telescoping substructure work on a drilling rig?

Telescoping substructures are lightweight and easily install and relocate. Hydraulics lift the mast into position. Spin-up substructures place the mast at ground level, and the substructure and mast raise into position together for operation via the use of screws.
