Drill bit into the well:
1. Check the rock drill bit flow path before the drill bit enters the well to prevent blockages;
2. When connecting the hard rock drill bit, be careful not to bump the cutting teeth, otherwise the life of the drill bit will be shortened;
3. In the case of drill-down, special care should be taken when the drill rock bit passes through the casing shoe and has a reduced diameter section;
4. When going down to the last single root, the pump should be opened in advance and slowly lowered. After the bottom of the well is drilled, the drill bit is lifted about 0.3 m from the bottom of the well and cycled for 5 minutes.
