苏德尔特油田潜山油藏数值模拟研究

Numerical simulation of the buried hill reservoir in the Sudeerte oilfield

采用双孔双渗模型,应用时变技术将开发动态与储层裂缝物性参数的变化结合起来,模拟裂缝性潜山油藏裂缝物性变化对开发效果的影响。分析并预测了潜山油藏在裂缝影响条件下的油水运移趋势和剩余油分布规律。在此基础上,通过预测不同井网形式及注水方式的开发效果来指导油田加密调整。根据苏德尔特油田的地质特征提出了井网和注水方式调整办法并取得了较好的开发效果。

The influence of different fracture properties on buried hill reservoir development response has been simulated with a dual-porosity dual-permeability model by using time variant technique.The trend of oil and water migration and remaining oil distribution is analyzed and predicted for buried hill reservoir under the condition of fracture influence.Prediction of the development responses of different well patterns and water injection schemes can guide oilfield infill modification.A modification plan of well pattern and water injection scheme has been proposed according to the geologic feature of the Sudeerte oilfield and has obtained good development result.
