What kind of environment is the main suitable for the rotary roller bit?
What kind of environment is the rotary cone bit（tricone bits） suitable for? There are many types of drill bits. As a tool for drilling rock formations, it has been widely used. The improvement of drill bit performance directly reduces drilling costs, especially in the past ten years. The two performance indicators of service life and drilling speed,
Rotary roller cone bit affects the degree of drilling cost. Increasing the drilling speed and service life of the drill bit is an effective way to reduce drilling costs. There are data confirm that the improvement of the drilling speed is a slower bit than the drill bit, that is, the speed of the cone is more The speed is lower than that of the drill bit. It is mainly used to scrape and break the rock. It is suitable for small hole drilling operations such as sidetracking and deepening of old wells under high speed and high drilling pressure. It plays an important role in drilling. The advantages of roller cone bits are: a wide range of applications, not only suitable for side drilling operations, but also can be used in medium and deep wells, showing important advantages in drilling. The working torque is lower than that of the PDC bit under the same WOB and formation conditions, which can reduce the problem of small-size drilling tool expansion and avoid down the hole accidents.
Rotary roller cone bits have the advantages of PDC bits and make up for the shortcomings of the two respectively. They are more suitable for formations with high strength and plasticity than roller cone bits. At the same time, they can also be used for hard interlayers and hard layers that PDC bits are difficult to deal with. Other complex formations. It is an ideal product.
