SFT-Ⅰ Silicon Fluorine Modified Asphalt for Drilling Fluid

Product Details

Silicon fluorine modified asphalt for SFT-I drilling fluid is the product of modified asphalt and silicon fluorine polymer. Adding drilling fluid into the product can greatly reduce the permeability of drilling fluid filter cake, reduce the filtration of drilling fluid, enhance the toughness of drilling fluid filter cake, reduce the friction resistance of drilling fluid, and enhance the lubricity. At the same time, it has a good sealing effect on the micro cracks of shale, reduces the hydration dispersion of shale, and has a good anti collapse effect. The introduction of silicofluoropolymer greatly improved the viscosity effect of the additive. The product has good compatibility and can be widely used in various water-based drilling fluids. The recommended dosage is 1.5-3%.
