Product Introduction
In oilfield hydraulic fracturing operations, customers often encounter problems such as high pumping pressure, insufficient proppant carrying capacity, low operational efficiency, and high costs.
Our anionic polyacrylamide (APAM) dedicated for fracturing fluids can significantly improve the rheological properties of fracturing fluids.
While ensuring construction stability, it achieves lower energy consumption + higher proppant carrying efficiency + better fracture conductivity.
This fracturing fluid thickener has become a core additive in fracturing operations.
Product Overview
Anionic polyacrylamide (APAM) is a high molecular linear polymer. In fracturing fluid systems, it is mainly used as a thickener and rheology modifier. By forming a three-dimensional network structure, it increases the viscosity and proppant carrying capacity of fracturing fluids, thereby optimizing fracturing performance.
Our anionic polyacrylamide (APAM) adopts a low-temperature homogeneous polymerization + controllable post-hydrolysis process. Using high-purity acrylamide as the monomer, polymerization is carried out under strictly deoxygenated conditions. It is specially designed for water-based fracturing fluid systems as a fracturing fluid thickener / fracturing fluid drag reducer / fracturing fluid proppant carrier.

Frequently Asked Questions (FAQ)
Q: 1. What is the main function of anionic polyacrylamide as a fracturing fluid additive?
A: As a fracturing fluid additive, APAM is mainly used as a thickener and drag reducer: on one hand, it increases fluid viscosity and enhances proppant carrying capacity; on the other hand, it reduces friction resistance in pipelines and improves pumping efficiency.
Q: 2. How to select molecular weight and ionic degree?
A: Recommended molecular weight: 8–20 million for fracturing applications.
High molecular weight products provide more significant viscosity enhancement; low hydrolysis degree products provide better drag reduction performance.
Specific parameters can be customized according to fracturing fluid water quality and operational conditions. Hydrolysis degree: 0%–35%.
Q: 3. What is the recommended dosage?
A: Recommended dosage for emulsion/microbead products: 0.25–2.0 gpt (gallon per thousand gallons).
The specific dosage should be determined based on fracturing fluid water quality, displacement rate, and operational requirements. Field testing is recommended for optimization.
Q: 4. What is the dissolution speed of the product?
A: Microbead products dissolve within 10–15 minutes, while traditional powder products require more than 1 hour.
This provides great convenience for on-site continuous mixing operations.
Q: 5. What is the applicable temperature range?
A: The effective operating temperature range is 5–50°C.
When fluid temperature exceeds 50°C and lasts more than 2 days, it is recommended to add a thermal stabilizer to maintain product performance.
Q: 6. Is it suitable for high-salinity fracturing fluids?
A: Yes.
Anionic polyacrylamide has good adaptability to changes in total dissolved solids (TDS) and can be used in fracturing fluids prepared with flowback fluid or produced water.
Q: 7. Will it damage the reservoir?
A: When used at a reasonable dosage, the product leaves no residue after complete gel breaking and has minimal impact on reservoir permeability.
Excessive dosage may cause polymer residue blockage in reservoir pores, so it is recommended to determine the optimal dosage through testing.
Q: 8. What precautions should be taken during use?
A: Powder products are hygroscopic; store in a cool and dry place below 35°C
Dissolution water temperature should not exceed 50°C to prevent thermal degradation
Avoid direct contact with strong oxidants and high-concentration metal ions
Emulsion products should be stored at 5–30°C to prevent freezing or demulsification
Wear protective equipment during operation to avoid contact with eyes and skin
Q: 9. What is the shelf life of the product?
A: Powder products have a shelf life of 2–4 years under cool and dry storage conditions; emulsion products have a shelf life of 6–12 months.
