【摘要】 结合流花11-1油田的岩芯、测井、地震、开发动态等资料总结了礁灰岩油藏沉积、成岩及构造等因素造成的储层非均质特征,引入的储层非均质综合指数,可更快速、直观地揭示了剩余油的分布规律。分析了控制剩余油分布规律的地质因素和开发因素。根据储层非均质性的综合研究成果,指出了剩余油潜力区;在潜力区部署的侧钻井生产情况较好,研究成果得到了验证。该研究思路对类似油田储层非均质性的表征与剩余油分布的预测有较好的借鉴作用。更多还原

【Abstract】 On the basis of core, well logs, seismic and dynamic data in Liuhua11-1 Oilfield, the characteristics of reservoir heterogeneity controlled by sedimentary environments, diagenesis, fault and fracture structures are described in detail.At the same time, a new concept of integrative index of reservoir heterogeneity( I _ RH ) is introduced and remaining oil distribution is predicted directly. According to the results of reservoir heterogeneity research, the enrichment regions of remaining oil distribution are stated and new sidetrack wells are proposed.The application of this method proves to be effective in Liuhua11-1 Oilfield and can be used in other similar oilfields.更多还原
