摘　　要：时移测井曲线重构是为满足储层时移地震研究需求,根据时移地震基础状态和监测状态的采集时间而对测井曲线进行后推或者前延的处理。以深水扇油藏水驱开发测井曲线重构研究为例,探讨了基于岩石物理研究的时移测井曲线重构的方法。通过分析在地震采集的不同时间点的地层含水饱和度的变化开展岩石物理分析,得到水驱过程中岩石物理参数的变化,重构得到不同时间点的测井曲线,并应用到后续的时移地震反演中。应用效果表明,时移测井曲线重构为后续时移地震反演提供了准确可靠的测井数据。Time-lapse logging curves reconstruction refers to the processing of logging curves to match the time-lapse seismic data acquisition time in base and monitor state.In this paper,we discuss the time-lapse logging curves reconstruction method based on petrophysical study.By analyzing the changes of formation water saturation at different time point of seismic data acquisition,petrophysical analysis can be carried out to get the changes of petrophysical parameters in the water flooding process,and then the logging curves at different time point can be reconstructed and be applied to subsequent time-lapse seismic inversion.The application shows that the reconstruction of time-lapse logging curves provides accurate and reliable logging data for the subsequent time-lapse seismic inversion.
