Study On Engineering Scheme Of Two Type Polymer Flooding Reservoir In Sa ? Group Of Western Part Of Section Three

With the planning arrangements of 12 th Five-Year Daqing oilfield productivity construction for Daqing oilfield in Western Saertu,South three oilfield productivity construction of two kinds of polymer flooding blocks in 2012,so this thesis focuses on the three South West SA group 2 of two type reservoir polymer flooding reservoir engineering design.This paper mainly analyzes the geology and reservoir sedimentary characteristics of the region,in the West South three district two reservoirs were well spacing optimization and wells optimization,respectively by 175 m,150m,125 m wells distance calculation of two kinds of reservoir sediment unit control degree,at the same time,3 different well spacing of wells the economic benefit evaluation scheme.The statistics of 7-12 two reservoir wells SA II 56 export(including oil production wells 37,19 injecting wells),further analysis of the two type reservoir polymer flooding effect on water flooding,the residual oil distribution of block,through the combination of comprehensive analysis and numerical simulation,optimizing combinations of layers,well spacing,for reservoir engineering design scheme of polymer flooding,maximize the two ultimate oil recovery.
