South Three Blocks In The Second Type Reservoir Numerical Simulation Of Polymer Flooding

Polymer flooding is an method to enhanced oil recovery，With the development of theoil industry. Polymer flooding have the earliest development and the greatest impact of thetechnology of enhancing oil recovery. Polymer solution can not only reduce the flow of waterto oil ratio, expand the swept volume of water injected in the reservoir, improve macro oildisplacement efficiency, but also improve microscopic oil displacement efficiency. In the oilfields of engineering generally considered EOR polymer flooding mechanism is to improvethe mobility ratio and improve sweep efficiency of macro, micro-polymer solution floodingmechanism is always the focus of attention of the oil workers. With the help of reservoirengineering and oilfield gather information on a comprehensive analysis of the actualinjection of polymer flooding index variation, the establishment of a structural model andsouthern areas of the test area138small block layers, sedimentary facies model, a small layerof each model by Phased corresponding attribute model.In connection with differentmicrofacies well group to evaluate of Polymer flooding. distributary channel sand, body sheetsand and non-body sheet sand Using different polymer concentrations can achieve betterflooding results.
