摘要:
川东山地表层条件复杂,地震接收条件变化非常大,形成了地震接收道低频和高频现象,影响了地震资料的有效频带。为了改善接收效果,提高单炮品质,基于耦合和振动理论,结合地震记录中的实际现象,对川东山地不同类型的低频道和高频道进行了分析,认为耦合系统的谐振频率、耦合系统的复杂性、耦合介质的非均质性及介质的共振是形成低频和高频道的主要原因。基于分析结果,提出了提高耦合谐振频率、减小共振、简化耦合振动系统阶数等技术方法,改善了接收效果。
Abstract:
Because of the complex surface condition in the eastern mountainous region of Sichuan,the receiving condition is changeable, thus,the low-frequency and high-frequency phenomena appeared in the tracks which affect the effective frequency band of seismic data.In order to improve the receiving effect and the quality of single shot, we analyzed the different type tracks of the low-frequency and high-frequency based on the coupling theory and vibration theory,combining the actual phenomena.It is considered that the main reasons that formed the low-frequency and high frequency are the resonance frequency of the coupling system, the complexity of the coupling system, the heterogeneity of the coupling medium and the resonance.So we can take some targeted measures such as increasing the coupling resonance frequency, decreasing the resonance,and predigesting the coupling vibration system,and so on.
