摘要: 对南海流花11-1油田储层层内、层间及平面非均质性进行了研究.在对储层非均质定量表征的方法中引入了储层非均质性综合指数概念,克服了以往研究工作中只应用单一因素表征储层非均质性的不足.利用该方法能够更准确反映储层的实际情况,进而研究储层非均质性对剩余油分布的控制作用,快速、直观地进行剩余油分布预测.在综合分析了油藏动、静态因素的基础上,根据对该油田储层非均质性研究成果,提出了剩余油潜力区,并在潜力区部署了侧钻井位.实际生产情况与非均质研究结果一致,取得了明显的效果.该方法对类似油田储层非均质及剩余油分布和预测的研究和推广应用都有较好的借鉴作用.

Abstract: The reservoir heterogeneity of Liuhua 11-1 Oilfield was quantitatively characterized.On the basis of research on the internal,interlayer and plane heterogeneity of the oilfield,a new method for characterizing reservoir heterogeneity with integrative index of reservoir heterogeneity was introduced to overcome some defects in previous researches.This method is based on combination of three parameters including porosity,permeability and interlayer for describing reservoir quality and two parameters such as microfacies and faulting to describe geometric aspects of the reservoir.The remaining oil distribution can be predicted directly on clarifying the preferable connection between integrative index of reservoir heterogeneity and remaining oil saturation.On the basis of comprehensive analysis of dynamic and static data,some new sidetrack wells were programmed in the enrichment regions of the remaining oil.The application effects of this method in Liuhua 11-1 Oilfield are good and can be used in other similar oilfields.

Key words: reservoir heterogeneity, quantitative characterization, reservoir heterogeneity index, remaining oil, reef oilfield, Liuhua 11-1 Oilfield
