Polymer flooding laboratory study in high temperature and high salinity reservoir of Wen 209 Block in Zhongyuan Oilfield

In this article, the polymer adapted to high temperature and high salinity reservoir has been studied by indoor experiment mostly. The result of the study can widen the application domain of polymer' and provide technology and practice base to make polymer to be used in high temperature and high salinity reservoir. It has been proved that the association polymer AP-P3 has very good anti-high temperature, anti-high salinity and anti-shear property, and can 209 block in Zhongyuan Oil field. be adapted to polymer flooding in the reservoir of Wen
