Single cone drill bits have a wide range of applications, not only suitable for side drilling construction, but also for use in medium and deep wells.
The working torque is lower than that of PDC drill bits under the same drilling pressure and formation conditions, which can reduce the problem of small drilling tools bulging and avoid downhole accidents.
Single cone drill bit combines the advantages of three cone drill bit and PDC drill bit, while also compensating for their respective shortcomings. It is more suitable for formations with high strength and plasticity than three cone drill bit, and can also be applied to hard interlayers and other complex formations that are difficult for PDC drill bit to deal with.
Cooperating with downhole power drilling tools can meet the needs of high-speed and special drilling.
Simple structure, large bearing space, safe and reliable use, and easy miniaturization of drill bit size.
