The system has high inhibition,which can inhibit cuttings scattering and formation mud yielding from mud shales;has better capabilities of lubrication,resistance to mud packing and reservoir protection effects;may make biodegradation.

Study and application of polyglycol seawater drilling fluids with strong inhibition;

Research results show that the drilling system features in high compatibility with other drilling additives and strong inhibition,and prevents wellbore instability effectively.
