The Waterflooding Dynamic Analysis Of Zhang Guan Miao Oilfield

Zhang guan miao oilfield and most oil field using the development way of water injection to maintain pressure, but due to the complex geological conditions, how to achieve the best effect of water flooding is more critical problem.Therefore to oilfield water injection development for dynamic analysis,Scientific and reasonable evaluation of water injection development effect,to further improve the waterflood development and enhancing ultimate oil recovery is of great significance.This article through to Zhang Guan Miao oilfield long4+5reservoir fine geologic and reservoir characteristics research,by the method of combine the static data and dynamic information fine described reservoir connectivity, property distribution,demonstrate the existing water injection development parameters are reasonable and the adaptability of the existing wells network; analysis Zhang Guan Miao oilfield long4+5reservoir pressure changes, evaluation of water injection wells affected extent and the cause of the water ratio of single well rise through the whole dynamic analysis and typical block production dynamic analysis;by water flooding dynamic analysis method and the material balance method, analysis of water storage rate and water ratiochange, Prediction of recovery degree、recoverable reserves and recovery ratio, find out the main influencing factors of the adverse oilfield development,Put forward the Suggestions for further research reasonable optimization of water injection adjustment program provided a basis.
