单牙轮钻头

单牙轮钻头是一种ofdeceleration位，这是圆锥体的速度比的速度ofdrill较小，主要是无序切削碎岩。 它适用于旧wellsidetracking和深化在高rotaryspeed和钻压的小井眼钻井作业。

1.其应用领域很广， notonly适于侧钻井，并且可以用于在深井。

2.工作转矩高于同一drillingpressure和形成条件PDC钻头低。 它可以减少小大小的洞expansionbuckling问题，使避免井下事故的发生。

3.单牙轮钻头具有优势ofboth三牙轮位和PDC钻头，并弥补了两者的缺点。 它ismore适合大型的塑料形成超过三牙轮钻头，也可以beapplied硬夹层其PDC钻头不能处理其他复杂的形成。

4，可实现高速和specialdrilling与井下电机。

Single Cone Bit

Single cone bit is a kind ofdeceleration bit, which is the speed of cone is smaller than the speed ofdrill, mainly disorderly cutting broken rock. It is suitable for old wellsidetracking and deepening the slim hole drilling operation under high rotaryspeed and drilling pressure.

1. Its application field is wide, notonly suitable for side drilling, and can be used in deep well.

2. Work torque is lower than PDC bit in the same drillingpressure and formation condition. It can reduce the small size hole expansionbuckling problems, so that avoid down hole accidents.

3. Single cone bit has advantages ofboth three cone bit and PDC bit, and make up the disadvantages of both. It ismore suitable for large plastic formation than three cone bit, also can beapplied to hard interlayer which PDC bit can not deal with other complex formation.

4. It can realize high speed and specialdrilling with down hole motor.
