Abstract: Analyzed study situation of oil displacement mechanism of moveable gel and polymeric system,and its applicable condition and flow rule were also studied,summarized general classify and characters of polymer gel.Proposed that it is needed to study flowage relationship by fragment experiment to determine apparent viscosity during study on moveable gel flow through porous medium,and it is needed to determine phase flow changes under apparent viscosity,and account for moveable gel through displacement with fragment experiment view.This study can provide direction to study on moveable gel flow rule and enhanced oil recovery.
