Synthesis and property evaluation of a new co-polymer for polymer flooding in high salinity high temperature reservoirs

摘要

Polymer flooding is one of most cost-effective methods tonsignificantly improve oil recovery for many mature oilfields. However,nconventional polymer can not be applied in high temperature and highnsalinity formation due to their low tolerance to high temperature andnhigh salinity. This paper will introduce the systhesis process and thenevaluation results for a new terpolymer which has been successfullynsynthesized in lab and successfully applied in high temperature andnhigh salinity reservoirs.
