【摘要】：埕岛油田馆陶组上段油藏进入中高含水期后,受储层非均质性强、水线不均匀突进、多井组生产相互干扰严重等因素的影响,注入水在地下驱替不均衡,直接影响油藏的整体开发效果。为此,提出合理产液量及注水量矢量优化方法,建立驱替突破系数的概念,确定均衡驱替界限为驱替突破系数等于3,并将实际油藏驱替模式分为4种,确定适用于不同驱替模式下的油水井合理产液量和注水量,达到实现油藏均衡驱替的目的。应用该方法在埕北11N井区的7个井组进行了矿场提液试验,截至2015年12月累积增油量为2.7×10~4t,预计评价期内(15a)采收率可提高5%。
[Abstract]:After the upper member of Guantao formation in Chengdao Oilfield enters the middle and high water cut stage, due to the influence of strong reservoir heterogeneity, uneven waterline penetration and serious mutual interference in the production of multi-well group, the uneven displacement of injected water in the underground directly affects the overall development effect of the reservoir. Therefore, the optimization method of reasonable liquid production and water injection vector is put forward, the concept of displacement breakthrough coefficient is established, the equilibrium displacement limit is determined that the displacement breakthrough coefficient is equal to 3, and the actual reservoir displacement mode is divided into four kinds to determine the reasonable liquid production and water injection of oil and water wells suitable for different displacement modes, so as to achieve the purpose of reservoir equilibrium displacement. The method was used to carry out the field fluid extraction test in seven well groups in Chengbei 11N well area. by December 2015, the cumulative oil increase was 2.7 脳 10 脳 4 t, and the oil recovery was expected to be increased by 5% during the evaluation period (15 a).
