【摘要】 以胜利渤深6三维地震资料为例,研究了针对资料特点如何优化资料以适应叠前时间成像的方法与措施,着重阐述了时间—空间域内分频随机噪音衰减等4种数据优化处理方法。该优化组合使低、高频随机噪音得到了有效衰减,并解决了波形差异问题,还使资料中深层有效频率和有效能量得到了加强。更多还原

【Abstract】 The methods that how to optimize the data to match the prestack time imaging based on the data specialty are studied taking the Shengli Boshen 6 block as an example. Four data optimization processing methods are mainly expounded such as fractional frequency random noise attenuation in time-space domain. The optimized combination effectively attenuates the low and high random noise, the wave- shape difference are solved. The effective frequency and energy of the data in the middle and deep parts of the section are improved.更多还原
