SFT-I钻井液用硅氟改性沥青是改性沥青和硅氟聚合物配合的产物。该产品加入钻井液能大大降低钻井液滤饼的渗透性,降低钻井液的滤失量,增强钻井液滤饼的韧性,进而降低钻井液的摩擦阻力,增强润滑性。同时对泥页岩的微裂隙有好的封堵作用,减少泥页岩的水化分散,有好的防塌作用。硅氟聚合物的引入,大大改善了该添加剂的粘度效应。该产品配伍性好,可广泛用于各种水基钻井液中,推荐加量1.5~3%。

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%.
