Our company SINO MUD push out a drilling fluid: Polyamine Amine based PSH. PSH is substitute of ULTRAHIB and KLA-HI of MI-Swaco. It’s a poly-amine-modified polyether polyols shale inhibitor, a new type of high-performance water-based drilling fluid shale Inhibitor.
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.
