无尘拖链Abstract: Aiming at the problems of insufficient inhibition and poor environmental protection performance of most shale hydration inhibitors, an acylated tea saponin (ATS) shale hydration inhibitor was synthesized by hydrophobic modification of tea saponin through acylation reaction. The inhibition properties of ATS on shale hydration were studied by immersion tests, linear swelling tests, shale cuttings hot-rolling dispersion tests and capillary suction time tests. The inhibition mechanism was analyzed by surface tension test, infrared spectrum analysis, contact angle experiment and micro morphology analysis. The experimental results showed that ATS was superior to potassium chloride and polyether amine in inhibiting hydration and dispersion of shale; ATS was adsorbed on the surface of shale through hydrogen bonding to form a hydrophobic layer; the surface tension of 1
% ATS aqueous solution was 35.89 mN m which significantly reduced the capillary force and reduce the water molecules invasion into shale; ATS was non-toxic, environmentally friendly and biodegradable.
Key words: ATS; Acylation reaction; Shale inhibitor; Ecofriendly
