The Research of the Dynamic Model of Oil Film in Pores

Abstract:

As a mature tertiary oil recovery technology, polymer flooding has been widely used in domestic oilfields, especially in Daqing oilfield, its polymer flooding production has reached more than 25% of total output. Therefore, there are important theoretical significance and application value to do further research of polymer flooding mechanism and use to guide the production. In order to understand the mechanism of polymer flooding, polymer flooding oil film based on the decrease of residual oil range is the biggest, established the dynamics model of polymer solution displacement of rock wall oil film under the condition of tensile and shear flow. In addition, this paper discussed the effect of the oil film thickness, tensile index, dimensionless tensile coefficient as well as the power-law coefficient on oil film start, and pointed out macroeconomic conditions which is the oil film start required.
