The efficiency and convenience of modern lifestyle rely on petroleum products that are extracted thousands of feet deep into the crust of the earth. This process involves drilling very deep wells into the surface of the earth to access oil deposits and other petroleum products. Very sophisticated methods and pieces of equipment are used in the drilling process. The drilling equipment is usually comprised of several parts and one of the most important components is the oil rig drill bit.
The components which do the actual cutting of soil and rocks in the drilling activity are called drill bits. These tools are made in such a way that they can cut through hard rocks and other materials in the ground to reach petroleum and gas. The bits are placed on the tip of drill string, right below the drilling pipe and collar.
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.
Percussion drilling is different from rotary drilling in many ways. In percussion drilling, a huge weight is continuously lifted and dropped in the wellbore to chip away at the rock and soil. In contrast, rotary drilling uses a rotating mechanism to scrape, cut, crush, and grind rock located at the bottom of the well. The system that does the job usually comprises of a hoisting apparatus, prime mover, drilling fluid, rotating equipment, drilling collar, and bits.
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.
There are several types of drilling bits. Steel rotary bits are among the most common. The other kinds are insert bits which are made of steel with tungsten carbide inserts. Normally, polycrystalline diamond bits are compact bits attached onto carbide inserts which are made from synthetic diamonds.
Diamond bits are the strongest bits in the market and they are 50 times stronger than their steel counterparts. They are used to drill through extremely hard surfaces. Besides the various types of bits named above, there are also hybrid bits which are used by combining different materials together. Hybrid bits are usually used to tackle specific challenges in different drilling situations.
Also, there are different kinds of drilling designs which are used in order to achieve varying results. Some of the designs are fishtail bits, core bits, and mill bits. This bits have different uses in the drilling activity. The material in which the drilling bit is made from will determine its price.
