| Property: Potassium Asphalt Sulfonate is partially water soluble and water dispersible. It acts to aid in stabilizing shale sections, controlling solids dispersion and improving wall cake characteristics. Unlike some other blending gilsonite, it is highly sulfonated by unique process which leads to partially oil soluble as well. This property gives more excellent emulsifying characteristic. It is also highly resistant to temperature. Potassium Asphalt Sulfonate stabilizes shale formation by inhibiting disintegration of the shale both chemically and physically. It inhibits the dispersion of drilling cuttings, controls high temperature high pressure (HTHP) filtration. It reduces torque and drag, prolongs the life of the bit, improves filter cake quality and enhances well productivity. It also acts as an emulsifier of diesel oil. In addition to providing the same unique quality as Sodium Asphalt Sulfonate, Potassium Asphalt Sulfonate contributes water-soluble potassium ions to the mud system. This is beneficiary to those areas that require the specific action of potassium to adequately minimize water-induced clay swelling. It is a proven extensively used drilling fluid addtive having manyfine properties.Oil asphalt is basal raw material. It appears brown in easly breakable pieces or fluidized powder. It is density is 0.98g/cm3.It is parly wa-ter soluble partly oil soluble for every kind of drilling fluid. The product include two types of high water soluble sodium asphalt sulfonate FT, kalium asphalt sulfonate FT-K.

Usage:They can emulsify fresh water or sea water with oil, deperess the solidexpansion of drll chips, control HTHP FL,produces thin and tenacious mudcakes,helps maintain low shearing rate under HThp, cleans and stabilizes well holes that have a great deal of collapsing shales. stabilize shale statum reduce rotative torque and prevent jamming substitute of oil, including crude oil,waste engine oil and dieserl oil depress the solid expansion of drill chips control HTHP EL produce thin and tenacious mud cakes Recommended quantity to be added: 1-4% Storage & Package:25Kg net,sealed in 3-in-1 compound paper bag with plastic lining. During sotorage and transporty see that the bag is intact as the product is water soleble. But its property is not affected even if it becomes damp. Key Words:Potassium Asphalt Sulfonate; Asphalt Sulfonate |
