The main purpose of rotary drilling is to perform well drilling and completion (preparation for production) by spending the least amount of money. Drilling rigs are divided into two classes, onshore and offshore rigs. Their main distinguishing features are mobility, adaptability for different operations, maximum drilling depth. The rig components are essentially the same for onshore and offshore rigs. The only major difference is that offshore installations have a pipe called a riser that connects the gas field to the wellhead on the seabed.
Drilling rotors work using a battery or hybrid engine. They are driven along with the drilling bit, which is used to replace the harmful gases in the initial drilling process. With technological advancements over the past century, drilling rotors have become more efficient and effective.
One of the first types of drilling rotors is the drill bit, which is used to bore down to the base of the indicated site. These rotors are traditionally used for opening up the borehole, lowering chains, and determining the indicated source. Drill bits are mainly used in mining rocks and mountains.
The second type of drilling rotors is the polycrystalline diamond compact (PDC) rotors, which are specifically used in the gas and oil industry. PDC rotors feature synthetic diamond teeth, and they work faster and more efficiently. These rotors are considered a crucial component of several drilling machines in gas extraction sites.
Finally, high-speed rotors are one of the last rotor types used in drilling activities. These rotors are globally used for gas and oil extraction. High-speed rotors are capable of generating enough force and torque to penetrate through the earth's crust and extract the desired material.
Key words: Polycrystalline Diamond Compact (PDC), Heavy Weight Drill Pipe(HWDP), Finite Element Analysis (FEA), Hot İsostatic Pressing (HIP).
