Buying Tips

How to choose a suitable drilling rig?

1. What will you do using drilling rig? 

---For water project, core sample, soil test, mineral prospect or others?

2. The depth you need?

---For water well, generally, 30-200m. For core sample, 30-600m, even more. 

3. Any requirements to hole diameter?

---Within a certain range, the smaller diameter, the deeper depth. Mathematically, we call it inversely proportional.

4. Working land condition?

A. soil, sand, weathered land, etc. soft stratum.
