| 摘 要： | 敖南油田M72水平井井区具有低渗透裂缝性油田特征,油田目前开发过程中水平井产量递减较快,为确保水平井井区的高效开发,对该区块不稳定注水方法进行了数值模拟研究.在应用Petrel地质建模软件与Eclipse数值模拟软件的基础上,对模拟区进行了精细地质建模与历史拟合,并设计了多种不稳定注水调整方案,以确定水平井不同储层、不同部位的合理注水强度以及合理注水周期,分别预测各方案的开发指标,对比不同方案的开发效果,最后综合各优化方案,总结出一套适合敖南油田水平井一直井联合开发的注水调整方案.结果表明,对于厚度小且渗透率低的储层适合采取对水平井加强指端注水、控制根端注水的方法,且指端与根端注水量之比为1.14,区块的合理注水强度为2.1 m3/(d·m),合理注水周期为3个月.

| Abstract: | The M72 horizontal block of Aonan oilfield has the property of low permeability and fracturing.In view of the present situation that production quickly declines during the process of development,the fluctuating injection is studied in this block with numerical simulation in order to maintain high efficient development in this area by means of horizontal well.Based on the software of Petrel and Eclipse,Detailed geological model is established and history matching is done,as well as many kinds of adjusting sc... |
