| 摘 要： | 在页岩气地球物理勘探中,反射地震方法具有勘探深度大,分层精度高和地震属性丰富等优点,是目前最常用的勘探方法之一。在分析山区页岩气原始地震资料波场特征的基础上,以提高叠加资料信噪比、分辨率和提高构造成像真实性为目的,通过对静校正、叠前去噪、子波一致性处理和偏移成像处理等主要步骤的对比研究,总结出最佳的处理流程和处理参数,获得了可供地质解释人员分析的高品质的地震成像剖面。

| Abstract: | In the geophysical exploration of shale gas,the reflection seismic method has the advantages of large exploration depth,high stratification accuracy and rich seismic attributes.It is one of the most commonly used exploration me thods.Based on analysis of wave field characteristics of original seismic data on mountainous shale gas,in order to improve the signal-tonoise ratio and resolution of stack data and improve structural imaging authenticity,through comparative study in static correction,pre-stack noise elimination,wavelet consistency processing and migration imaging processing,this paper sums up the best process and processing parameters,obtains high quality seismic imaging section available for analysis by geological interpreters. |
