摘　　要：针对埕岛油田馆陶组的开发现状及存在的问题,以埕北11井区为例,在进行提液可行性分析的基础上,给定实际的地质参数,利用非活塞式水驱油理论和单因素分析方法,确定最佳的提液时机和生产压差。应用油藏数值模拟的方法,对提液的技术界限进行了优化,给出了最佳的提液方案,并进行了效果预测。预测结果显示,15a增产原油165.7×10~4m^3,以综合含水率95%作为极限含水率,区块最终采收率为29.5%。In the view of the current development situation and problems in Guantao formation of Chengdao Oilfield,Chengbei 11 well block was analyzed as a representative case.Based on feasibility analysis on increasing liquid production,actual geological parameters were given.Non-piston like displacement and single factor method were applied to establish optimal enhancing liquid moment and production pressure differential.Technical limits of enhanced liquid were optimized with numerical simulation method.Finally optimal enhanced liquid scheme was assigned.After the scheme is implemented,165.7×10~4m^3 oil will increase in the next fifteen years,if composite water cut is 95%,ultimate recovery factor of this block will be 29.5%.
