Product function

1. can improve the rheological property of drilling fluid. The drilling fluid prepared by FA367 has good carrying performance and can obtain the best borehole cleaning effect.

2. highly inhibiting to shale.

3. has good thermal stability in the application of oilfield. Resistence to temperature over 180°C.

4. excellent calcium salt resistance.

5. can effectively prevent oil and gas reservoir pollution, increase oil and gas production.

6. has great adaptability.Suitable for fresh water, sea water, saturated brine and Other kinds of water -based drilling fluids.

7. good compatibility with other treating agents.

In-field use

The normal dosage of FA367 is 0.2-0.4% for fresh water and 0.7-1.5% for saturated saline slurry.
