| 摘 要： | 绥中36—1作为中海油主力注水生产、疏松砂岩稠油油田,提高采收率成为当前的主要技术方向。时移地震作为提高采收率的主要地球物理手段,使之成为主要的研究方向。本文阐述了我们利用已有的生产数据、油藏认识的可行研究,即利用动态及历史拟合的油藏模型,分析油藏可能时移地震响应,寻找时移地震响应在时空的分布特征。一方面可以分析在本地区应用时移地震技术的可行性;另一方面对第二次甚至第三次采集时移地震数据的时机进行分析。经过分析认为绥中36—1的时移地震响应除受到疏松储层的影响外,将受油藏脱气的影响。并认为生产10年后采集时移地震数据有相当的可行性。

| Abstract: | Field SZ36-1 is a water-flooded heavy oil reservoir with high porosity and unconsolidated sand. The recovery rate is low so that it becomes a challenge for production. Time-lapse seismic data is studied to improve the oil recovery for this field. This feasibility study analyzes the possible time-lapse seismic attribute spatial distribution using dynamic data and the reservoir model to determine the optimum time to acquire a new seismic survey. Based on the study, it is found that the time-lapse seismic response for this unconsolidated sand has a strong signature due to solution gas when the reservoir pressure is below the bubble point. This indicates that acquiring a new survey after 10 years of production is appropriate for a time-lapse seismic application. |
