【摘要】 在时移地震技术的实际应用过程中,限于观测条件及处理流程等因素的影响,不同时期所获得的地震数据的一致性往往是较差的.这些不一致通常表现为地震资料在振幅、时间延迟、频率、相位等方面的差异.为了消除这些差异带来的影响,通常使用的方法就是进行时移地震的互均化处理,本文讨论了一种有效的时移地震互均化质量监控方法,用来评定时移资料的优劣,互均化结果的好坏,能够为时移地震可行性分析及互均化处理流程带来一定的帮助,同时可以起到很好的指导意义.更多还原

【Abstract】 There usually to be lots of differences about amplitude,time lapse,frequency,phase etc.on repeatability between the time-lapse seismic data got form different years limited by observation system and processing flow.The paper proposed a new method based on correlation parameters for time lapse seismic non-repeatability analysis and quality control for cross-equalization processing.This method worked well with the time-lapse seismic records from a Chinese ocean oil field.The correlation parameters we selected and presented in this paper are proved effective for time-lapse seismic cross-equalization quality control.更多还原
