Product Description

Risol Polyhib is a poly-amine-modified polyether polyols shale inhibitor. Polyamine proposes good cationic adsorbability and inhibitory capacity and a long duration of action. Since the introduction of amines compounds to molecular chain, which give it   greater shale inhibition and its anti-collapse mechanism is different from the ordinary  polyether products, It mainly depends on the special structure which firmly adsorbs on the clay to reduce the clay layer spacing to prevent water from invading into the formation in order to stabilize the wall effect. The product can be directly added to all kinds of water-based drilling and completion fluids. The recommended treatment concentration is usually 0.5%–2.0%.

Technical Specification

Features

1.  It can effectively prevent from hydration swelling, brittle shale from peeling off the wall and bit balling for its excellent inhibition, By creating a hydrophobic film on the borehole wall and thus preventing water from entering into formations. Especially suitable for soft mud stone formation, salt formation and water sensitive formation.
2.  It has excellent lubricant capacity.
3.  It is suitable to apply in all kinds of mud system.
