检波器大地耦合响应的野外规模测量与衰减方法

Geophone Field Scale Measurement and Attenuation Method for Geodetic Coupling Response

在地震检波系统中,地表测量的主要目的在于接收地表的振动,而不是检波器外壳的振动,但受到技术条件的限制,目前应用的检波器都因耦合响应而影响了地震数据的保真度。本研究参考了国内外大量的研究文献,简要介绍了一种检波技术的设计思路、振动力学以及测量结果的模态参数,并通过分析耦合响应对地震数据的影响,探讨了相应的衰竭方法,即解耦反褶积。

In the seismic detection system,the main purpose of the surface measurement is to receive the vibration of the earth＇s surface rather than the vibration of the geophone shell,but the current geophone has affected the fidelity of the seismic data due to the restriction of the technical conditions. This study refers to a large number of research documents at home and abroad. The design idea of the detection technique,the vibration mechanics and the modal parameters of the measurement result are introduced,and the corresponding failure method,that is,the decoupling deconvolution,is discussed by analyzing the influence of the coupling response on the seismic data.
