Study On Numerical Simulation Of Polymer Flooding Experiment In Xing-13 Block

With the gradual mature of polymer flooding technique,numerical simulation technique and relevent software, and the gradual imperfectness of various allied technique as well as the scale of polymer flooding getting bigger and bigger year by year, polymer flooding has been a key technology support for the continuous high production in Daqing oil field and improving the development level during the late high water cut.period. In addition, the development of numerical simulation technique makes reservoir description more precise possible. Study on the numerical simulation of polymer flooding during the high water cut period is very important for improving the final recovery of polymer flooding further.According to the dynamic and the static features which include the position of wells,the data of subzones, the fruit of sedimentary facies ,the history of producers and injectors,the measures of producers and injectors as well as the tests of producers and injectors,etc. this paper sufficiently considers heterogeneity, distribution of sedimentary facies, adopts interpolation technique in phases for peameability, porosity and thickness, section reasonably for the properties of fluids and relative permeabilities and establishes a fine numerical simulation model for the experimental areas.We adopt Eclipse mazout simulator E100, Descartes coordinate system, block-centered grid, the fully implicit method to make history matching and program prediction during the waterflood period.We use the polymer flood model module in the Eclipse numerical simulation software and establish the polymer flooding mathematic model to study polymer flooding oil.What's more,we make history matching and program prediction during the polymer flooding.We choose the optimal program,which provides important guidance for the development and adjustment of oil field.
