1. Description
In the drilling process, the drill bit is the main tool to break the rock and the wellbore is formed by the drill bit breaking the rock. How well a wellbore is formed and the length of time it takes are not only related to the characteristics of the rock in the drilled formation and the performance of the drill bit itself, but also to the degree of mutual matching between the drill bit and the formation. Reasonable selection of drill bits plays an important role in increasing the drilling speed and reducing the overall cost of drilling.
The drill bit is one of the important tools for oil drilling work. Whether the drill bit adapts to the rock properties and its quality plays a very important role in the selection of drilling technology, especially in terms of drilling quality, drilling speed and drilling cost.
2. Specifications we can offer
At present, there are many types of drill bits used in the petroleum industry and mining industry. The drill bits are classified according to different drilling methods. They can be divided into PDC drill bits, roller cone bits, scraper bits and mining diamond coring bits. These drill bits are the most basic drill bits and we all can provide.
