The Study On Waterflooding Characteristic Of Weixing Oilfield In Low-to-moderate Cut Stage

The paper is aimed at the main contradiction of Weixing Oilfield. Take "drop decreasing and controlling moisture content" as the goal ,to implement the "11599" projects ,we use reservoir engineering theory and mathematical statistical methods to study the development situation, water flooding Characteristics of Weixing Oilfield and have mastered the production decline, the moisture content changes and the various potential of Weixing Oilfield.Besides, we have learned the difficulties, the favorable conditions, the control of production decline and the increase of the capacity of aquifers of that Oilfield during the "11th Five-Year Plan" period .We have given the recommendations to control aquifers and increase production.It will provide effective technical support for the latter part of the adjustment, the adjustment of the development of evaluation results and "11th Five-Year" Development Plan for the oilfield development. It will lay the foundation for the latter part of a comprehensive adjustment of oil fields and will offer important significance to the stability of oil production and long-term sustainable development to Weixing Oilfield.
