Study On The Project Of Jin271Block Profile Control And Flooding Test

Long-period water injection and oil recovery due to formation fluid seepage changes,such as the formation of fluid advantage channels make oil well producing water. After waterbreakthrough, moisture content keeps rising, oil recovery at the high water-cut stage into acollecting water, oil production decreases, profit squeezes, or even off production because ofits unprofitable. So it is necessary to make profile control and flooding of the water injectionwell to control the water quantity of high permeability layer, increase the water quantity oflow permeability layer and improve the injection profile, so as to enhance oil recovery.This text based on a comprehensive study of Jin271block reservoir geology, buildsreservoir geological model, spreads refined reservoir descriptions and fine numericalsimulation, apply reservoir production performance data and dynamic monitoring data,through history matching to get the underground distribution of remain oil. Meanwhile,analysis and study the agent that matched with reservoir environment, determine the profilecontrol system and profile control parameters of Jin271block. Apply RS optimization designsoftware, to choose comprehensive decision for the profile control wells, so as to make themost sensible solution.
