I. Product Overview
PF-PLUS is a copolymer of acrylamide and acrylate, which can adjust the flow pattern in drilling fluid to inhibit shale dispersion, resist inorganic ion pollution, reduce drilling fluid fluid loss, increase drilling speed, reduce downhole complications and reduce Drilling costs and other advantages. Not only can it be used in low-solid non-dispersed polymer drilling fluid system, but also in dispersed drilling fluid system.

III. Product function
1. PF-PLUS is a linear high molecular polymer, which can maintain a small n value after adding drilling fluid, and can effectively adjust the flow pattern.
2. Good shear thinning performance.
3. Compared with hydrolyzed polyacrylamide, it has better anti-collapse and coating properties.
4. It can effectively reduce the filtration loss of drilling fluid.
5. Good anti-pollution and temperature resistance.
6. Non-toxic and non-flammable.
IV. On-site application
Since the successful development of PF-PLUS, it has been popularized and applied in more than a dozen oilfields across the country, including Shengli, Liaohe, North China, Xinjiang, Jilin, Changqing, Zhongyuan, and Dagang, and has achieved huge social and economic benefits.
The usual dosage is 0.2-0.4% for fresh water slurry and 0.5-1.5% for saturated salt water slurry.
V. Packaging
Packed in three-in-one bags, with a net weight of 25 kg. During storage and transportation, care should be taken to prevent rain, moisture, and damage to the packaging.
