Potassium Asphalt Sulfonate is partially water
soluble and water dispersible. Potassium Asphalt Sulfonate acts
to aid in stabilizing shale sections, controlling solids dispersion
and improving wall cake characteristics. Unlike some other blending
gilsonite, Potassium Asphalt Sulfonate is highly sulfonated
by unique process which leads to partially oil soluble as well.
Potassium Asphalt Sulfonate gives more excellent emulsifying
characteristic. Potassium Asphalt Sulfonate is also highly resistant
to temperature. Potassium Asphalt Sulfonate stabilizes shale
formation by inhibiting disintegration of the shale both chemically
and physically. Potassium Asphalt Sulfonate inhibits the dispersion
of drilling cuttings, controls high temperature high pressure
(HTHP) filtration. Potassium Asphalt Sulfonate 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. Potassium Asphalt
Sulfonate is a proven extensively used drilling fluid additive
having many fine properties. Oil asphalt is basal raw material.
It appears brown in easily breakable pieces or fluidized powder.
Its density is 0.98g/cm3. Its partly water soluble partly oil
soluble for every kind of drilling fluid. Potassium Asphalt
Sulfonate includes two types of high water soluble: Sodium Asphalt
Sulfonate FT, Calcium Asphalt Sulfonate FT-K.

Usage:
Potassium Asphalt Sulfonate can emulsify
fresh water or sea water with oil, depress the solid expansion
of drill chips, and control HTHP FL. Potassium Asphalt Sulfonate
produces thin and tenacious mud cakes, 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
Packing
25Kg net each, sealed in 3-in-1 compound paper bag with plastic lining.
