Oilfield Drilling Used Polyacrylamide

1.Product Brief

Polyacrylamide is a copolymer of acrylamide and acrylate, which can adjust the flow pattern in drilling fluid to suppress 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.

2.Physical and chemical properties

3.Product function

(1)Polyacrylamide can prevent the hydration and exfoliation of soft mud shale and hard brittle mud shale, and stabilize the well wall; after adding drilling fluid, it can maintain a small n value and can effectively adjust the flow pattern.

(2)Has good shear thinning properties.

(3)Polyacrylamide has better anti-collapse and coating properties.

(4)Polyacrylamide can effectively reduce drilling fluid filtration loss.

(5)Has good anti-pollution and temperature resistance.

(6)Applicable to various water-based drilling fluids such as fresh water, sea water, and saturated brine.

4. On-site application

Since the successful development of Polyacrylamide, 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.

5. 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.
