This paper briefly introduced the progress in time-lapse seismic as shown from the 76th SEG annual meeting. Topics include the repeatability of time-lapse seismic, in which we discussed the effects of shooting and receiving environments on repeatability, the effects of the cable length and its positioning accuracy and stability on repeatability, and the data processing techniques to improve repeatability, new insights into time-lapse seismic, in which we described tube wave time-lapse response, spectral decomposition, and time-lapse VSP monitoring, and problems related to application of time-lapse seismic technology. The comprehensive applications of time-lapse seismic and other geophysical data were demonstrated with the real data from an oilfield. Finally, we summarized the difficulties in using time-lapse seismic and outlooked its future trend.

简要介绍了第76届SEG年会反映的时移地震技术的进展，主要内容有：时移地震的可重复性，讨论了激发、接收环境对可重复性的影响，海上拖缆长度、定位精度及排列稳定性对可重复性的影响，以及通过数据处理技术提高数据的重复性；时移地震技术的新领域，讨论了管波时移地震监测、谱分解技术和时移VSP监测等；简要分析了时移地震技术应用中应该注意的问题，并通过时移地震在某个油田的实际应用，讨论了时移地震技术与其他地球物理手段的综合应用；最后分析了时移地震技术目前存在的问题，展望了其发展趋势。
