The convenience and efficiency of the modern lifestyle depends mostly on petroleum products which are extracted deep in the crust of the earth. In order to extract these products, it requires drilling deep in the earth to reach the petroleum products and oil deposits. The equipment used normally comprises of various parts and among the most essential components is the oil rig drill bit.
When drilling, rocks and soil is cut by the drill bits. The bits are designed with the ability to cut through rocks as well as through other ground materials. This makes it possible for gas and other petroleum products to be accessed. Below the drilling collar and pipe there is the drill string on whose tip the bits are located.
Drills are designed so that they can rotate as they excavate. The bits are comprised of two or three cones that are made using some of the hardest materials on earth. The materials that are commonly used to make cones are diamond, tungsten carbide, or steel. The diamond used may be natural or synthetic. The cones have very sharp teeth that cut into rocks and soil in the ground.
Rotary drilling is different from percussion drilling in numerous ways. Percussion drilling involves continuously lifting and dropping a huge weight in the well to chip away soil and rock. On the other hand, rotary drilling involves rotating mechanisms which cut, scrape, crush and grind rock at the bottom of the well. This system normally achieves this using a combination of drilling bits, drilling collar, hoisting apparatus, rotating equipment, drilling fluids and prime mover.
The power needed in the drilling process is generated by the prime mover while lifting of the drill pipe is done by the hoisting equipment. Lifting of the pipe needs to be done to insert or remove it from the well. Rotary motion is used by the rotating equipment to move other components. The drilling string is kept floating during the process by drilling fluid, which also lubricates the entire process. Chippings are also removed from the well by the fluid.
Drill baits are of several different types. The most common ones are the steel tooth rotary bits. Another type are the insert bits which are made of steel but have tungsten carbide inserts. Polycrystalline diamond compact bits are usually attached to carbide inserts and they are made from synthetic diamonds.
As compared to steel bits, diamond bits are the hardest bits available in the market. These bits are 50 times stronger than those made from steel. Normally, they are used to drill very hard surfaces. Apart from the different bits mentioned above, there are hybrid bits which are made by combining various materials. These kinds of bits are used to deal with specific challenges in various drilling conditions.
In order to achieve varying results, drilling can be done using various designs. Mill bits, core bits and fishtail bits are some of these designs. In the drilling process, different purposes are accomplished by different designs. The material used to make the bits determines how much they cost.
