A rotary rig is a popular instrument used for drilling wells. A rotary drilling machine comprises different parts including an engine, a hosting as well as a mud rotating and circulating system. The operating component of a rotary drilling tool has three systems – lifting, rotation and circulation. Different Types of Drilling Machines There are different types of drilling rigs easily available in the market. Your choice should be based on your particular needs. Drilling rigs are used for different purposes. However, the main purpose of using such a rig is to create ground holes. The rigs used to drill water wells, natural gas wells or oil wells feature massive housing equipment. Compared to this, a portable drilling machine is smaller in size. These are also called auger. These small drilling machines are widely used to examine physical properties of rock, soil or groundwater and sample mineral deposits. The easy-to-carry machines also find an extensive use in installing fabrication on instruments, tunnels, wells or other underground utilities. Drilling rigs are installed on tracks, trucks and trailers. These are also mounted on land or marine-based structures such as oil platforms popularly known as offshore rigs. Portable drilling rigs are extensively used in water wells, environmental investigation and mineral exploration. The bigger drilling tools can be used to drill through thousands of crust. These can easily circulate mud through drilling. You will find a huge variety in land-based drilling rigs. These drilling rigs are mostly used for exploration activities. Conventional drilling machines are heavier than slim hole rigs. There are other types of drilling rigs as well. One such variety is called Coiled Tubing Rig. Coiled Tubing Technology is used in making of these rigs. The rigs have pipes of continuous length and these pipes are stored on pools. There are benefits of using such types of rigs as they significantly reduce drilling waste and equipment footprints. These rigs are particularly useful in the environmentally sensitive areas. The Coiled Tubing Rigs are also used for making a re-entry into existing wells and if multiple casting in the wells is deemed unnecessary. And then, there are Jack up Rigs. These are particularly useful in shallow water bodies with depth less than 300 feet. This type of drilling rigs resembles a floating barge having a long-legged drilling structure. Drill ship is widely used for offshore exploration. It can drill nearly 10, 000 feet in water. Final Words Requirements apart, price should also be a consideration before making a purchase, especially if you are buying a portable drilling machine for personal use.
