Research On The Waterflood Development In Baima Xianyao-miaoju Oil Region

Since june2011,four wella have been waterflood in Bai ma yao xian-miao ju Oil region,in which Ding4052has been waterflood at april2010,Ding4055-land4056wells have been waterflood at june2010,Dingzhu4015-1has been waterflood at june2011.The Average single well daily injection rate is15m3/d,and some oil wells have been effective.As the injector producer distance became greater,it needs a longer effective period which about5months.when the wells have been effective,the oil production can be increased about twice,indicating the waterflooding is feasible.But there are some wells due to injection layer bit corresponds to less extent,has yet not been effective.Because of that situation,we research、statistics and analisis of the waterflooding development information.we analysis of the conditions and geological features of exploration and development of oil zone, and analyzed the characteristics of well testing and producing test,thus consolidated the main problems in oil field development.we proposed effective waterflood development programs,and the feasibility of the waterflood program was evaluated in order to achieve the purpose of increasing production and stable production,it will be better to guide the oilfield development.
