Classification And Selection Of Drill Bits

At present, there are many types of drill bits used in the petroleum industry. The drill bits are classified according to different drilling methods. They can be divided into diamond drill bits, roller cone bits and scraper bits. These three types of drill bits are the most basic types of drill bits. Among the three types of drill bits, the most common and widely used one in oil drilling is the roller cone bit, which has a relatively deep application. Comparing these three kinds of drill bits, the one with the smallest range of use is the scraper drill bit. This article mainly introduces diamond bits and roller cone bits.
