阿南低渗透油藏开发特征及剩余油分布预测

方法 以阿南油田为例，从钻井、地质、地震、测井、开发动态资料入手，以小层为单元，用数值模拟的方法，重点剖析了阿３１断块剩余油潜力分布，并提出扩边挖潜区块。目的 为低渗透油田的开发提供参考，并为阿南油田的稳产提供地质依据。结果 指出侈渗透油藏的开发特征及开发中存在的问题。预测了剩余油分布富集区，实现了油田的稳产。结论 低渗透油藏开发时应注意注采系统的匹配、井网的适应性；多套井网开发区应以各种调整措施

Development features of A''''nan low permeability reservoir and prediction of its residue oil.

Method Starting form related in formation, e.g. drlling, geology, seismic, logging and development performance, potential residue oil distribution of A'31block is thoroughly studied with member as unit and with the aid of numerical simulation. Purpose To provied reference for further development of low permeability oilfield and geological accordance for maintaining production. Result Not only found development features and problems existiong in tapping resources of low permeability reservoirs, but predicted accumulation area of residue oil and achieved stabized production. Conclusion In developing low permeability reservoirs, matching of injection-production systems and adaptability of well pattern should be paid enough attention. For fields with a number of well patterns, various adjusting measures, such as fracturing and acidizing, should be given priority in improving oil productivity; or specialized study on hard-to-produce reserve be performed for fields developing withs single well pattern.
