Study of EOR Method about Marginal Heavy Oil Reservoir in Shengli Oil Field

The Chenjiazhuang Reservior in Shengli Oil Field is a typically heavy and high permeability reservoir, which resulted in a relatively poor oil increment by the universal thermal stimulation. By the geologic research and the developmentanalysis, robust water injection according to distribution of remaining oil andhydrodynamic, matching techniques as well as careful reservoir management, were all contributed much to oil recovery, which comes true that oil production annually held steady going with a bit of rise. The comprehensive water percentage was steady, the oil exploration effect was obviously improved, and the recovery efficiency increased 5.6%.
