摘　　要：大庆A1A2项目中PCEDM地质油藏模型不能完全满足油田数据存储、应用要求,分析地质油藏模型及其表间关系,并与中国石油模型地质油藏部分对比,得到模型间存在对现实对象的抽象认识不同、命名冲突等差异点,提出在保留PCEDM设计风格基础上进行模型调整和扩充的思路,并给出模型扩展、制定数据映射规则、修改数据表结构、在概念模型上调整数据表间关系等4种解决方法.结果表明,使用这些解决方法修改模型取得良好的效果,为模型的应用奠定基础.The PCEDM geological reservoir model can’t satisfy the practical requirements of field data storage and application in A1A2 project of Daqing,in order to achieve on-line application of PCEDM geological reservoir model as soon as possible,the relationship between tables of PCEDM model was studied,and the geological reservoir part of PCEDM model was compared with that of PetroChina model to find whether there exist points of difference such as the different abstract cognition and naming conflicts to real objects between different models.Model adjustment and expansion on the basis of retaining design style of PCEDM,a train of thought,was proposed to solve problems about the points of difference.Four solutions such as model expansion,development of data mapping rules,modification of data table structures and adjustment of relationship between different data tables were presented.After practical verification,the integrated use of the above methods to modify the model has achieved good results.This study results lay the foundation for further optimization of the model and data migration,and promote the application of the model as soon as possible.
