摘要
针对尕斯库勒油田N1-N21油藏面临自然递减快、水驱效果差、水驱情况认识不清、以及认识层次较低等问题,利用分流量曲线分析法对该油藏进行了详细的水驱分析,得到各个开发阶段的水驱前缘、前缘含水饱和度、平均含水饱和度等数据,并以此为基础计算水驱效率,为提高油田开发的可控性及提高最终采收率提供极有价值的资料。目前油藏正在进行二次开发和调整,分流量曲线分析法极大地指导了油田开发,产生了较好效果。
The gasi N1-N21 reservoir is the biggest production res-ervoir of Qinghai oilfield,the main problem of the reservoir is that nature depression decline quickly,water displacement effect is lower,water flooding is unclear and recognition is low.We carried on detailed water flood analysis with factional flow curve method and gained water flood front,front water contend saturation,average water saturation of different stage.On the base of that,we can calculate the flooding efficiency,which provided valuable data to improve the control ability of development and final recovery rate.Now the reservoir is going through second development and adjusting.Factional flow curve method is very useful to oil field development and proved good effect.
