时间推移3-D地震监测是一种新出现的优化烃类生产的有特征的监测技术,该技术能监测储层流体流动期间所产生的地下岩性变化。文中讨论了产油储层中,与三相流体流动有关的物理理论以及流体流动压力、温度和孔隙饱和度值与地震P波和S波速度的岩石物理转换关系。通过弹性波动方程模拟和成像理论,将流体流动物理参数与地震反射振幅和旅行时联系起来。模拟结果表明,利用不同开采时期的重复地震勘探可监测流体的变化并将这种变化成像。 Time-lapse 3-D seismic monitoring is a new and emerging monitoring technique that optimizes hydrocarbon production, which monitors changes in underground lithology that occur during reservoir fluid flow. In this paper, we discuss the physical theory related to the flow of three-phase fluid in oil-bearing reservoirs, and the petrophysical relations between fluid pressure, temperature and pore saturation and P and S wave velocities. Through the elastic wave equation simulation and imaging theory, the physical parameters of fluid flow are related to the seismic reflection amplitude and travel time. Simulation results show that using repeated seismic surveys of different mining times can monitor fluid changes and image this change.
