【摘要】 以中国南海东部某开发油田为例,论述了精细油藏描述和油藏数值模拟一体化研究技术实现油田滚动开发评价。其中在储层精细描述过程中,主要通过精细地层对比、地震信息约束地质建模技术等研究,建立了较为精细的、能够客观表征储层内部特征的三维地质模型。在此基础上通过油藏数值模拟研究中的生产历史拟合,发现地质模型中存在的不确定性因素,将信息及时反馈到模型中,通过地质、油藏一体化研究,实现地质模型的合理调整与优化。在精细油藏描述的基础上,制定了合理、高效的开发调整方案,为油田的挖潜和最终采收率的提高奠定坚实基础。更多还原

【Abstract】 This documentary take some developed oilfield in China southeast sea as example to demonstrate the application of integrated technique of detailed reservoir description and reservoir numerical simulation in oilfield rolling development. In detailed reservoir description, 3D geological model which is relatively fine and objectively representing internal character of reservoir is built mainly by means of strata correlation, technique of geological modeling restricted by seismic information. On the basis of geological model, some uncertainties of geo-model could be figured out by history match in numerical simulation. The feedback of uncertainty can be put back into geo-model to make the it more reasonable by the idea of geology and reservoir integration. On the basis of detailed reservoir description, design feasible and efficient development project is designed so as to guarantee the successful oilfield development and improvement of final recovery.更多还原
