深井观测地震波的研究

A Study on the Propagation of Seismic Wave Observed by Downhole Seismometer

本文系统地总结了我国深井观测地震波的运动学和动力学特征,即从地面与井下以及土层与岩层,分别就地震波振幅、走时、频谱、波场等方面做了讨论,并用软盖层效应加以统一解释。本成果已在台站建设、资料分析、震源参数测定、油田裂缝定位和介质结构参数测定等方面发挥了作用。

In this paper, the authors have summarized the kinematic and dynamic character of seismic wave observed by downhole equipment in our country. Seismic wave amplitude, travel time, spectrum and wave field are discussed respectively on ground and downhole, in soil layer and rock layer, and explained unifiedly by softly covered layer effects. This research achievement has been used in building seismic stations, analyzing data, locating fracture in oil field and determining parameters of seismic focus and of medium structures.
