Bentonite plays an important role in the drilling process, mainly including:

Carrying cuttings: During the drilling process, pieces will inevitably fall off the well wall, and a large amount of cuttings will also be produced when the drill bit and the ground are cutting. Bentonite mud can carry these fallen blocks and cuttings out of the well along with the drill pipe, keeping the bottom of the well clean.

Protect the well wall: Bentonite is an important material for making drilling fluid. It has good mud-making ability and can produce a large amount of high-viscosity mud. This kind of mud can penetrate, bond, and reinforce the loose soil layer, pure sand layer, and rock layer gaps and pores on the well wall, thereby effectively protecting the well wall and preventing hole collapse.

Cooling drilling tools: When the drilling pressure is too high, high temperatures will inevitably occur when the drill bit cuts hard rocks on the ground. At this time, some bentonite mud can be driven into the bottom of the well, which can effectively cool the drill bit, lubricate the drilling tools, and prevent the drill bit from burning due to overheating.

Reduce drilling pressure: Bentonite mud has strong lubricity, which can significantly reduce the phenomenon of excessive drilling resistance and incomplete drilling, and improve the drilling rate.

Anti-collapse: When completing drilling, injecting high-viscosity mud into the ground that is prone to collapse can prevent the ground from collapsing.

In addition, bentonite also has many other functions, such as improving the safety and reliability of pile walls and serving as an important component of petroleum organic drilling fluids.
