摘要:
针对时移地震定量研究难题，提出了一套岩石物理模板构建技术，并应用于时移地震可行性分析和剩余油分布定量预测。该技术是在井资料的约束下，通过Hertz-Mindlin接触模型结合Hashin-Shtrikman界限模型得到与地质特征匹配的岩石物理模板，并通过改变孔隙度、泥质含量、流体性质、温度和孔隙压力等参数模拟各种条件下含油饱和度变化后各种弹性参数的变化规律，进而用于时移地震定量研究。S油田的实际应用表明该技术的预测结果与实钻结果有较高的吻合程度。
In this paper, a technique of rock physics template construction is proposed and applied in time-lapse seismic feasibility analysis and quantitative prediction of remaining oil distribution. Based on well data, the Hertz-Mindlin contact model and the Hashin-Shtrikman lower bound model, forward modeling with different parameters such as porosity, shale content, fluid properties, oil saturation, and temperature and pore pressure was carried out to get data for rock physics template. With the rock physics template matched with geological features, we can get quantitative regulation between elastic parameters and oil saturation under various conditions, which can be used for time-lapse seismic interpretation. The practical application shows that the time-lapse seismic prediction is in good agreement with the well drilling results in S oilfield.
