| Abstract: | Aiming at the shortcomings of the CBM air drilling that rubber core of swivel control head are easily damaged and hexag- onal kelly are needed to be equipped, simple swivel control head has been developed. Field application shows that this device can use the original drilling tools and quartet kelly, have longer seal life and operate easily. Using this device can promote efficiency and cost savings. |
