EOR Applications:

EOR enhanced oil recovery in oil fields over 30 years of history. Polymer flooding and polymer flooding is related to chemical EOR technology in important ways. Field application results show that polymer flooding technology, the use of one ton of polymer can yield 150 tons of crude oil, which is in the reservoir by injecting a viscous polymer solution, reducing the injected water "fingering" or "breaking into" trend and improve the injection profile and improve sweep efficiency of injected water eventually delay "breakthrough" to achieve enhanced oil recovery purposes.

Shandong Tongli different reservoir salinity, temperature, different oil viscosity and reservoir permeability, by adjusting the molecular weight of the polymer, charge density, molecular structure was developed to meet the different reservoir conditions corresponding product.
