For The Characteristics Of High Water Cut Stage In Daqing Oilfield In Xingbei Development Area

In China, the vast majority of oil fields are currently facing the development of high water cut period or even for determining development, how to keep oil field for determining high yield and stable yield, will focus on water flooding development characteristics of oil-water two phase flow. This article through to the oil field for determining oil-water two phase flow characteristics, dynamic development characteristics, reservoir engineering method and the method to improve water drive recovery factor research, indicates that determining the oilfield with high water cut period different development patterns; analysis of the telative permeability curve in Xingbei development area,water cut period of liquid production index, development adjustment measure changes of water absorption index and the rate of increase of water development in different periods; put forward the extra high water cut stage technical direction and the suggestion for the main of enhancing the recovery ratio. The results of this study verified the theory of oilfield development, quality, benefit and guide oilfield sustainable let hair is of great significance.
