Amine Based Shale Inhibitor PSH


      High-performance Shale Inhibitor




Product Description













Amine based PSH, a new type of high-performance water-base drilling fluid shale inhibitor of my company, is a poly-amine-modified polyether polyols shale inhibitor. Amine based PSH proposes good cationic adsorbability and inhibitory capacity and a long duration of action. It has overcome the problems which caused by cation, such as serious flocculation, increase water loss and so on. 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 adsorbes 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%.
