Reserach On Polymer Flooding In Three Types Reservoir Of Lamadian Oilfield

Lamadian oilfield is one of the earliest promation of polymer flooding in daqing oil field.The end of the first of polymer flooding reservoir development at present.Polymer flooding oil industrial development has been carried out.Three kinds of reservoir has become the main oilfield eor potential layer.Lamadian oil field is mainly in the delta,three kinds of reservoir development and outer front facies,sand body surface stability,which has many,thin layer,poor permeability,heterogeneity,differences in the characteristics of small,tely on water flooding development difficulty,the mathematical model to predict water flooding water cut reached 98%,the ultimate recovery degree at around 40%.Laboratory research shows that three types of reservoir flooding can increase oil recovery by 7%.Research high counter reservoir reasonable injection parameters of polymer flooding,polymer flooding reservoirs ability,the dynamic regularity of polymer flooding reservoirs,reservoir comprehensive adjustment of polymer flooding technology,and economic benefit evalution table is high polymer flooding reservoir.
