Abstract
In order to increase the oil production and ultimate recovery of Xingbei area of Daqing oil field, according to the geologic conditions of Xingbei region .The reasonable injection parameters of polymer flooding were discussed considering geologic information , experiments in lab, economic benefit . The study consists of analyzing the law governing of the remaining oil in Xingbei. By applying the methods of the combination of geological modeling and simulation for analyzing different polymer molecular weight, concentration, dosage and injection rate. concludes the influence of different injection parameters to ultimate oil recovery, This paper provides a theoretical basis and experimental support for apricot north polymer flooding of Xingbei area of Daqing oilfield .
