What do the hardness and complexity of the stratum specifically refer to?
The hardness of a formation is primarily the solidity of the rock or soil, which affects the speed and difficulty of the drill rig's drilling.
In general, harder formations may require more powerful Drilling Rigs and longer drilling times.
And the complexity of the formation can include the following:
1. rock type:
Different types of rocks have different hardness and properties.
2. formation structure:
Such as tilting, folding and faulting of the strata.
3. fissures and pores in the rocks:
They may affect the distribution and flow of groundwater.
4. heterogeneity of strata:
there may be zones of varying hardness.
5. the degree of rock fragmentation:
More fractured rocks may make drilling more difficult.
6. the presence of special substances:
Such as fossils, minerals, etc.
All these factors will affect the difficulty and time of drilling, and it is very important to know the hardness and complexity of the formation before drilling in order to choose the right drilling rig and drilling method.
