Polyethylene Glycol


In drilling fluids, polyethylene glycol has strong inhibitory, blocking and lubricating effects. It is the main component of polyol drilling fluids. It has a permeability effect, improves the viscosity of drilling fluid filtrate, reduces the activity of water in the drilling fluid to reduce pressure permeability, stabilizes shale and prevents wellbore instability. Polyethylene glycol can also be used separately as an inhibitor and blocking agent.
