Product overview
XY-27 is used as a viscosity reducer (or deflocculant) in drilling fluids.A certain proportion of cation, anion and non -anion functional groups were introduced into its molecular chain.The presence of cationic groups greatly improves the XY-27′s ability to inhibit the dispersion and expansion of shale and enhance the inhibition of drilling fluid system. Therefore, XY-27 can not only significantly reduce the viscosity of drilling fluid, but also keep the viscosity of drilling fluid stable, showing strong anti-cuttings pollution ability.
