1. Steeltooth位具有效率高

传统的钢齿牙轮钻头的牙2.耐磨性不好，齿形结构优化不足，从而导致降低ofaverage ROP的。

3. STseries钢齿位以高效率可以解决这些问题， withstrong耐磨牙齿和快速的ROP ，位可以工作更稳定地，这ismore适于钻软或中间软地层具有高rotaryspeed 。

4. Applicationof ST系列钢齿钻头高效率是解决theproblem提高钻井速度的井高出部分的最佳方式

5. STseries钢齿位以高效率可以解决这些问题， withstrong耐磨牙齿和快速的ROP ，位可以工作更稳定地，这ismore适于钻软或中间软地层具有高rotaryspeed ..

的SWT系列位Thesize范围是从8 1/2到17 1/2英寸， IADC而变化from117至127 。

1. Steeltooth bit with high efficiency

2. Wear resistance of teeth of conventional steel tooth cone bit is not good, tooth shape structure is lack of optimization, which leads to decrease ofaverage ROP.

3. STseries steel tooth bit with high efficiency can solve these problems, withstrong wear resistant teeth and fast ROP, bit can work more stably, which ismore suitable for drilling in soft or middle soft formations with high rotaryspeed.

4. Applicationof ST series steel tooth bit with high efficiency is the best way to solve theproblem of increasing drilling speed in higher part of well

5. STseries steel tooth bit with high efficiency can solve these problems , withstrong wear resistant teeth and fast ROP, bit can work more stably, which ismore suitable for drilling in soft or middle soft formations with high rotaryspeed..

Thesize range of SWT series bit is from 8 1/2 to 17 1/2 inch , and IADC varies from117 to 127.
