Study on the law and application effect of variable fluidity polymer flooding to enhance oil recovery
No.3 Production Room, Geological Institute, No.2 Oil Production Plant, Daqing Oilfield Co., LTD, Heilongjiang Daqing 16300 China
At present, our country most of reservoir with low permeability, strong heterogeneity and poor sand body development characteristics, so for maximizing the aggregate material oil displacement effect of technology on the basis of reservoir play, need on polymer flooding experiment foundation of the converter combined with oil displacement wall and degree of control theory and flow theory, polymer qualitative drop sticky technology is put forward. This paper first analyzed the introduction of variable fluidity polymer in detail, combined with the principle of variable fluidity polymer technology, summed up the experimental process and results of variable fluidity polymer flooding enhanced oil recovery.
Key words: Variable fluidity polymer / Recovery factor / Technical personnel / The technology principle
