Product Introduction
After oilfields enter the middle and late stages of development, they generally face problems such as high water cut, low recovery rate, and declining oil displacement efficiency.
Our anionic polyacrylamide (APAM) is used for EOR (tertiary oil recovery). By increasing the viscosity of injected water and enhancing mobility control capability, it effectively expands the sweep volume and significantly improves crude oil recovery.
This tertiary oil recovery polymer ensures that every unit of injected water "drives" out more oil, reducing the operating cost per ton of oil.
Product Overview
Our anionic polyacrylamide (APAM) adopts a low-temperature homogeneous polymerization + post-hydrolysis process, using acrylamide as the monomer, and polymerizing under strictly deoxygenated conditions.
The molecular weight range is 20–28 million, and the hydrolysis degree of 20%–35% can be customized. It is specifically used as a polymer flooding agent in oilfield oil displacement processes.
By increasing the viscosity of the displacement fluid and improving the water-oil mobility ratio, more efficient oil displacement can be achieved.

Product Advantages
Improved Recovery Rate = Direct Revenue Increase for Customers
By increasing the viscosity of injected water and improving the mobility ratio, reducing the "water channeling" phenomenon
→ Expand sweep volume
→ Increase crude oil recovery rate (typically increased by 5%–15%)
As a mobility control agent for polymer flooding, this product can effectively improve the water-oil mobility ratio and enhance oil displacement efficiency.
Reduced Water Injection Cost = Improved Project Economics
Higher efficiency means less ineffective water injection
→ Reduce energy consumption
→ Reduce water treatment pressure
→ Improve overall return on investment
Stable Molecular Structure = Low Usage Risk
Through optimized polymerization process, the molecular chain structure is more stable
→ Strong shear resistance
→ Maintain performance under high salinity and high temperature conditions
This temperature-resistant and salt-resistant oil displacement agent performs particularly stably under complex reservoir conditions.
Customizable for Reservoir Adaptation = Easier Project Success
Products can be customized according to different oilfield conditions (temperature, salinity, permeability)
→ Improve adaptability
→ Reduce customer trial-and-error cost
→ Increase project success rate
Applications / Solutions
-
Polymer flooding: Increase water phase viscosity, improve mobility ratio, and expand sweep volume
- Binary/ternary compound flooding: Used with surfactants to improve both sweep efficiency and oil washing efficiency
- Profile control and water plugging: Selectively enter high-permeability layers and improve water absorption profile
- As a polymer for compound flooding, this product shows significant synergistic effects with surfactants in binary/ternary flooding systems.
