摘　　要：以沙南油田梧桐沟组油藏为例,详细阐述了油藏描述与数值模拟一体化技术的实现方法。首先通过油藏描述技术建立三维地质模型,并在综合分析模型不确定性的基础上选择符合油藏实际的地质模型作为数值模拟的输入;其次应用网格粗化技术,再结合生产动态建立油藏数值模拟模型;最后在历史拟合的基础上,主要针对影响油藏开发效果的不同开发方式进行指标预测和效果评价,提出油藏合理的开采技术界限。应用油藏描述与数值模拟一体化技术,提高了数模中地质模型的精度和质量,为优选开发方式和剩余油分布研究提供了可靠的技术保证。Taking Wutonggou reservoir in Shanan oilfield as an example,a method for realization of integrated technology of reservoir description with numerical simulation is expounded.Firstly,the3-D geologic model is developed by using reservoir description technology,based on integrated analysis of the mode uncertainties,selecting a suitable geologic model for actual reservoir as input data of numerical simulation.Secondly,the reservoir numerical simulation model is developed by using gridding technology integrated with production performance.Finally,the reasonable technical limit for reservoir recovery is proposed by index prediction and effectiveness evaluation based on the history match and different recovery processes affecting reservoir development efficiency.Applying the integrated technology of reservoir description with numerical simulation can improve the accuracy and quality of geologic model during numerical simulation,and provide reliable technical guarantees for the optimization of development process and the in-depth study of remained oil distribution.
