Abstract
Polymer solution rheology experiment showed that the rheology of polymer solution used in Daqing Oilfield obeyed power law pattern. This paper presents the percolation equation and its modification used for liquid producing Leservoirs flooded by polymer,presents the determination method of producers’ IPR curve in polymer flooding. Case study indicated that the Vogel equation could not be used to predict well productivity in polymer floodlng; yet, the value calculated by this method matched well with the measured value.Therefore, this method is reliable for predicting well productivity in polymer flooding.
