Sulfonated Asphalt


It's a proven extensively used drilling fluid additive having many fine properties. Oil asphalt is basal raw material. It appears brown in easy breakable pieces or fluidized powder. It's partly water soluble, partly oil soluble and partly both water and oil soluble, having fine emulsifying property suitable for every kinds of drilling fluid. Our factory is the first manufacturer who produces these related products in China.FT-1A is a modified product through technical innovation. Its performance is much better this content decides its performance in mud. So it's absolutely necessary to increase the content of asphalt

HTHP FL (ml/30min)



They can emulsify fresh water or sea water with oil, depress the solid expansion of drill chips , control HTHP FL, produce thin and tenacious mud cakes, help maintaining low shearing rate under HTHP, clean and stabilize well holes that have a great deal of collapsing shale.

1) stabilize shale stratum

2) reduce rotative torque and prevent jamming

3) substitute of oil, including crude oil, waste engine oil and diesel oil

4) depress the solid expansion of drill chips

5) Control HTHP FL

6)produce thin and tenacious mud cakes

7) Recommended quantity to be added: 1-4%

4. Storage package

25Kg net sealed in 4-in-1 compound paper bag with plastic lining. During storage and transport see that the bag is intact as the product is water soluble. But its property is not affected even if it becomes damp.
