Characteristics

1. Low fluorescence lever, easy to distinguish and discover petroleum and gas reservoir.

2. Excellent anti-caving effect and can keep borehole regular.

3. Improve mud cake quality and lower filtration loss.

4. Enhance the ratio of yield value to plastic viscosity, effectively improve the ability of cuttings carrying, achieving the best effect of borehole cleaning.

5. Good high temperature resistance ,suitable in deep and ultra deep well.

6. Good compatibility with polymer drilling fluid system.

7. Simple application method on site; directly added or mixed with water.

8. Common dosage is 1 -3%.

Notes

Light handle when transport .Stored in a dry and ventilated place and kept off rain and sun.If splashing into eyes,flush with water.

Package

It is packed in kraft paper sacks, with net weight 25kg per sack.
