The blast hole rotary parts Diaries
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 done on land.
Apart from extracting petroleum, they can be used in the construction industry in building foundation construction, roadbed, airports and bridges constructions where strong foundations are required. They can also be used in mining, water and drilling well drilling. The drilling rigs come in different types and the most suitable is selected according to the task that is at hand. The drilling rig classifications can be done using various factors, technologies or attributes.
By power
The kind of power a drilling rig uses can determine what type it is. In general, you can find mechanical drilling rigs which use clutches, transmissions and torque converters that are powered by their 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 which are powered using pressurized air.
By Pipe
Rig categorization under pipe has cable drilling rigs that use cables to raise and drop drill bits, conventional drilling rigs which use plastic or metal drill pipes of different types to suit the function and col tubing rigs that use giant tube coils and down hole drilling motors.
By height
When temporarily removing drill pipes from the hole and is based on the number of connected pipes in the derrick, height categorization comes in. Single rigs pull dingle drill pipes, whereas double rigs can handle a stand of pipe that has two connected pipes in 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. There are also rotary table rigs that achieve rotation by turning a square or hexagonal pipe at 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. You will also find hammer rigs that use percussive and rotation force.
By derrick position
Drilling rigs can also be categorized according to the positioning of the derrick on the equipment. There are conventional 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.
Whatever the drilling needs you have, there is always an importance of making sure you select the best for the task at hand. When you know what your options are your chances of choosing the best drilling rig are increased. We find different sort of drilling rig for sale in the market. Your choice of rig depends on your specific need. Drilling rigs are those machines which are used to create ground holes. These can be of massive structural housing equipment that are used for drilling oil wells, natural gas wells and/or water wells. Alternatively, these can be smaller ones which can be carried manually by a single person. These are named as auger. These are used to sample mineral deposits on the sub-surface, test physical properties of rock, soil and groundwater.
These can also be used for installing fabrication on a sub-surface basis, just like instrumentation, wells, tunnels and underground utilities. Drilling rigs are also mounted on trucks, trailers or tracks. Alternatively, these can be mounted on more permanent marine-based or land-based structures like oil platforms which are popularly called offshore rigs. They are called so even if without a drilling rig for sale.
The different types of drilling rigs for sale can be small and portable, just like the ones which are used in mineral exploration, environmental investigations and water wells. Because conventional well rigs can be used for drilling projects on a long-term basis, these focus on their portability. The bigger drilling rigs for sale can drill through hundreds and thousands of Earth's crust. These large amounts of mud pumps generally circulate slurry mud through drilling. There are several other kinds of drilling rigs like land based ones. These are, in fact, the most often used one for any kind of exploration. This rig is used for drilling land based ones. Slim hole rigs are slimmer than conventional drill bores.
Other drilling rigs for sale include Coiled Tubing rigs. This uses the technology of coiled tubing where pipes with continuous length are used to be stored on large pools. This is highly beneficial as it reduces drilling waste as well as minimizes equipment footprints. This type of rigs is highly beneficial in areas which are environmentally sensitive. It can be used for re-entering into existing wells and also when any kind of multiple casing is unnecessary in wells. Jack up rigs are used in water bodies which are relatively shallow. This is used in water bodies which has its depth less than three hundred feet. It is a kind of floating barge which has a drilling structure with long legs. Drill ship is used for farther offshore explorations. This can drill almost 10,000 feet in water.
There are also hydraulic rigs which use hydraulic power, steam rigs which use engines and pumps that are steam powered and the pneumatic ones which are powered using pressurized air.
The drilling technology classifies the drilling rigs into non rotational rigs that include most service rigs and direct push check here rigs.
