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。
Using dual-porosity and double-permeability model, the time-varying technique was used to combine the development dynamic with the change of physical parameters of reservoir fractures to simulate the influence of physical property changes of fractured buried hill reservoirs on development effectiveness. The tendency of oil and water migration and distribution of remaining oil in buried hill reservoirs under the influence of fractures were analyzed and predicted. Based on this, we can guide the oilfield encryption adjustment by predicting the different well pattern and the effect of water injection. According to the geological characteristics of Sudeerte oilfield, the paper puts forward the adjustment methods of well pattern and water injection and has achieved good development results.
