摘要: The rheological characteristic of polymer solution directly influences the oil displacement efficiency in process flooding, and it is necessary that characteristics used flooding are researched. Loss modulus storage with different mass concentration relative molecular studied relationship between them analyzed through steady dynamic shear experiments. first normal stress difference at low angular rate calculated based on loss modulus, combined obtained by flow experiments high rate. differences a wider range can be set up. results show established wide feasible. higher or is, coefficient is.
