Mining & Oil Drilling

Drilling fluids need to provide sufficient viscosity and interfacial activity to form a stable filter cake on the wellbore, improving the compressive and shear resistance of the wellbore walls. Otherwise, the mechanical abrasion from the drill bit and hydraulic erosion from fluid circulation can cause severe wellbore caving and collapse, burying the drill bit and preventing further drilling progress. Choosing effective shale inhibitors like guar gum, CMC, and maltodextrin is critical.

High-quality lubricant additives can form lubricating films and reduce the coefficient of friction between the drill pipe and wellbore walls. This creates a hydrodynamic lubrication effect under dynamic conditions, minimizing frictional drag on the drill string and preventing it from getting stuck due to wellbore collapse or cuttings accumulation. Selecting lubricants with excellent stability at high temperatures and pressures is effective for preventing sticking problems during drilling.

For different corrosive gases, selecting effective corrosion inhibitors and explaining the inhibition mechanisms, combined with using heat transfer fluids, can significantly reduce the corrosion rate of casing and drill tubings under high temperature and pressure downhole conditions, prolonging their service life. Otherwise, severe tubing corrosion can lead to oil leakage and other safety hazards.
