SFY- Ⅰ Silicon F luorine S hale I nhibitor for D rilling F luid

P roduct D etails

The silicon fluorine shale inhibitor for sfy-i drilling fluid is an additive for drilling fluid with the introduction of organosilicon fluorine polymer. The additive can be adsorbed on the surface of clay particles to form a hydrophobic layer when it is added to the drilling fluid. Therefore, it can prevent and weaken the hydration and dispersion of clay and has a better inhibition effect. The product has good compatibility and can be used in various water-based drilling fluids. The recommended dosage is 1-3%.
