The Adaptability in Polymer Flooding to GuoPu Oilfield of Childers - Jayne Childers

Abstract:

In view of the actual conditions of childers - jayne GuoPu reservoir with low temperature, high salinity , this text select three kinds of polymer by evaluating the related parameters of polymer which is resistant to high salinity to discuss the performance and adaptability.From the polymer viscosity-concentration relationship and viscosity-temperature relationship, it can be concluded that when the concentration of the HDSJ is 3000 mg/L, it can meet the requirements of the theory of reservoir viscosity values.However, due to the specific conditions of reservoir with high salinity (249060mg/L), the single polymer HDSJ cannot continue to maintain theory viscosity value.In view of the problems of polymer degradation at high salinity, those experiences join the mass fraction of chromium acetate 2.7% with retarder, to cross-linking in a single polymer solution based on 30:1 polymer chromium rate. By testing the stability of cross-linking system, we can conclude that HDSJ gel solution with polymer chromium ratio 30:1 can meet the reservoir conditions.
