Main Advantages:

1. High drilling efficiency;
2. Timely sampling and high rate of adoption are conducive to accurately assessing the stratum;
3. Using higher grade carbides for longer life;
4. Minimizes hole erosion in fragile formations
5. Drills faster through soft formations with less blockages
6. Drills straighter through consolidated and unconsolidated formations
7. When drilling in the aquifer, the blockage of the pore wall by the mud can be avoided, and the original natural permeability of the formation can be maintained. The reverse circulation drilling can use various materials such as hard alloy, diamond, cone and scraper bit. Different rock fragmentation tools can be used for cyclic flush drilling of various rock fragmentation methods such as rotary drilling, impact drilling and impact rotary drilling, and the flushing medium can be clean water, mud or air. Can drill into the vertical hole, inclined hole or horizontal hole, can drill into all kinds of strata.

Why do you need to set back injection on reverse circulation bit ?
According to the way of mud circulation, the rotary drilling machine is divided into positive circulation drilling and reverse circulation drilling. Positive circulation drilling is that the mud is pumped out of the mud pool by the mud pump, the input hose is sent to the upper entrance of the hollow drill rod, and the hollow drill rod is sprayed to the bottom of the drill bit. The rotating drill bit lubricates the mud.
