Abstract: Moveable gel displacing oil technique is a developing technology of enhanced oil recovery. this article introduced a testing research, which was carried out in common heave oil and high water formation, offered injecting shear loss about surface flow, gave surface and underground performance of moveable gel displacing oil, analyzed reactions of oil and water wells,measured the increased yield of testing well using tracking numerical simulation, appraised testing result using two economic appraisal methods.Our research indicated the testing result is evident, the total increased yield is 2.01×10 4 t in one and a half year, wining the total investment. We have established method of evaluating the effect of gel displacing oil, provided great significations for the exploitation of resemble oil layer.
