Overview
Polyamine modified polyether polyols shale inhibition with cations strong adsorption, strong inhibition, special anti-sloughing mechanism and long active duration properties. Its special structure can be adsorbed on clay to reduce the clay interlayer space and thus prevent the water enter into the formation.
