Abstract:
According to the reservoir characteristics of upper mem-ber of formation V in Shuanghe oilfield,a 3D geological model has been established. Through production history matching with ECCLIPSE software,a three-dimensional and two-phase digital-simulation software,the impact study on physical and numerical parameters towards en-hanced recovery in polymer flooding has been studied so as to define the threshold value of various parameters in field ap-plication,provide theoretical basis for the selection of poly-mer,and achieve the fullest effect of polymer flooding pur-poses.
