摘      要：In this work,shale hydration Inhibition performance of tallow amine ethoxylate as a shale stabilizer in water based drilling fluid,was investigated through these tests:bentonite hydration inhibition test,bentonite sedimentation test,drill cutting recovery test,dynamic linear swelling test,wettability test,isothermal water adsorption test,and zeta potential *** results showed that bentonite particles are not capable of being hydrated or dispersed in the mediums containing tallow amine ethoxylate;tallow amine ethoxylate had shown a comparable and competitive inhibition performance with potassium chloride as a common shale stabilizer in drilling *** amine functional groups exist in tallow amine ethoxylate structure which are capable of forming hydrogen bonding with surfaces of bentonite *** phenomenon decreased the water adsorption on bentonite particles surfaces which results in reduction of *** amine ethoxylate is also compatible with other common drilling fluid additives.
