时移地震属性分析技术的基本框架

油气田勘探与开发阶段中的地震资料解释越来越依赖于地震属性分析技术，但2个阶段的地震属性分析又存在许多的异同点。在现有时移地震属性分析技术的基础上，通过渤海SZ361油田时移地震油藏监测过程的实际应用，提出了一套较为完善的时移地震属性分析技术系列，并进一步明确了油藏监测中时移地震属性分析的重点研究内容是时移地震的敏感属性分析，地震属性分析各个环节的质量控制和时移地震差异的属性综合解释。这对于油藏监测中进一步开展时移地震工作，挖掘和发挥时移地震的作用和潜力具有一定的实际价值。

Basic framework of time-lapse seismic attribute analysis

Seismic data interpretation has become more and more depending on seismic attribute analysis in the exploration and development stage of oilfields, but there are many similarities and differences between these two stages in the seismic attribute a-nalysis. Based on the present time-lapse seismic attribute analysis techniques and with the practice of time-lapse seismic reservoir monitoring in Bohai SZ36-1 oilfield, this paper put forward a set of more perfect time-lapse seismic attribute analysis techniques, and showed that the key to time-lapse seismic attribute analysis in reservoir monitoring is to determine the sensitive attributes, the quality control of each stage in seismic attribute analysis, and the integrated interpretation of time-lapse seismic difference attributes. This will be of certain actual value in deploying time-lapse seismic, and exerting the potentials of time-lapse seismic in reservoir monitoring.
