SFT-I鉆井液用硅氟改性瀝青是改性瀝青和硅氟聚合物配合的產(chǎn)物。該產(chǎn)品加入鉆井液能大大降低鉆井液濾餅的滲透性，降低鉆井液的濾失量，增強鉆井液濾餅的韌性，進而降低鉆井液的摩擦阻力，增強潤滑性。同時對泥頁巖的微裂隙有好的封堵作用，減少泥頁巖的水化分散，有好的防塌作用。硅氟聚合物的引入，大大改善了該添加劑的粘度效應。該產(chǎn)品配伍性好，可廣泛用于各種水基鉆井液中，推薦加量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%.
