Product Introduction
Poly-Surfactant
1. Application Areas
The poly-surfactant developed by our company is based on a highly salt-resistant polymer. By incorporating an appropriate amount of lipophilic groups, the polymer’s macromolecular chains are engineered to simultaneously possess both hydrophilic and lipophilic groups—that is, the macromolecular chains exhibit an amphiphilic structure. This confers a certain degree of surface activity, providing both excellent viscosity-enhancing properties and strong emulsifying capabilities. Consequently, it increases recovery rates by improving the oil-to-water flow ratio and expanding the volume of the injected fluid to increase recovery rates, as well as by leveraging its emulsifying and dispersing functions to improve oil displacement efficiency and thereby boost recovery rates. The poly-surfactant is currently widely used in the Daqing Oilfield, and pilot tests are underway at the Dagang and Shengli Oilfields.
2. Product Characteristics
Emulsifying performance is one of the key characteristics of active polymers. Emulsification and dispersion can improve oil displacement efficiency, while emulsification and thickening can further increase the viscosity of the polymer solution, improve the flow profile, and expand the volume of oil displacement. This performance is determined by molecular structure and cannot be achieved simply by physically blending polymers and surfactants. The oil-loving groups of active polymers can penetrate oil droplets and become adsorbed as a whole at the oil-water interface, significantly enhancing the mechanical properties of the interface and reducing the probability of oil droplet collision and coalescence, thereby improving emulsion stability. Furthermore, since the emulsification mechanism of active polymers is entirely different from that of surfactants, the demulsification process is relatively simple, as demonstrated by numerous field trials.
High-efficiency viscosity-enhancing performance is also one of the key characteristics of active polymers. Concentration-viscosity tests conducted under simulated oilfield wastewater conditions indicate that the viscosity of active polymer solutions is more than 50% higher than that of polyacrylamide under the same conditions, resulting in significant savings in polymer usage and costs.
