A Study On Effect Of Waterflood Development And The Precise Limits Of The Water Injection Technology In Xing6 West Block

The xing 6 west block depends on fine technology of tapping potential technology of water flooding which with the “666” subdivision water injection as the core.It has a good effect that the year of water at most 1 percent and natural decline or many years controlled about 7 percent,keeping the water flooding production at about60 percent.With the development of oil field,original technology standards in the application process not fully meet the demand for oilfield development.Needing precision injection technology,explori g extra high water cut period offurther improving the accuracy of water injection technology and methods.This combination of field research to establish a geological model and Numerical Simulation Model,and evaluate for reservoir production status from horizontal and vertical foration.According to the actual production relationship of oil and water wells in each layer,and on the base of considering vertical factors for an in-depth study on the influence of horizontal influence factors on the development effect of water flooding,and identify the main factors and weights.Using reservoir engineering method and combining with water flooding condition of each section of water well to determine remaining oil potential and precise water injection scheme of each well pattern.Meanwhile,for to further determine the development effectiveness.On the basis of subdividing water injection,combining the different remaining oil potential with reservoir characteristics of different sections of water wells to give the best combination mode of measures.Application of numerical simulation software to predict to water recovery rate of 98%,compared to the lack of measures taken,a 0.75 percent increase in oil recovery.
