Title: RESEARCH ON WATER INJECTION TECHNOLOGY FOR VISCOUS CRUDE IN ULTRA-DEEP WELL
Abstract: Ordovician carbonatite heavy oil reservoir in Lunxi Oilfield has been developed since 2001,its reservoir pressure declines rapidly,producing energy is made a loss severely,so,the flush stage of Lunxi Oilfield is very short.In order to improve the producing capacity of heavy oil reservoir,water injection technology used in ultra-deep well has been applied since 2008.Through water injection production in 18 wells in 2009,cumulative incremental oil was high up to 5.5×104 t,the recovery ratio was improved remarkably.By the data analysis of water injection technique in Lunxi oilfield,some measures were given for the future water injection production.
