Engineering Research Of Chemical Flooding In Honggang Oilfield

Jilin Oilfield EOR based on the understanding of previous research,fully learning the Daqing oilfield EOR pilot encountered technical problems and early test for polymer flooding problems, Honggang carry out engineering research in the north part .Engineering Research of Honggang Oilfield research and evaluate underground separating injection process . Determnate the separating injection processing . In field test,understand of the separate injection process in the cutting degradation of polymers, form on the viscosity loss of polymer underground well simulation in software and technologies of eccentrically separating injection . Simulate the viscosity losses in the initial vertical pipe flow and distribution through the injector and embrasure . Viscosity loss of separating injection process is less than 5% . Design the Seal Section of offing and fastening. Lay a solid foundation for the EOR in Jilin Oilfield .
