本文从地震波在地层中的传播特性出发，对配备Σ-ΔA／D转换器的新型地震数据来集站中与高分辨地震勘探数据采集有关的几个重要参数，如采样率、动态范围、前放增益、输入噪声、畸变等进行了说明，并分析了它们之间的相互关系。核心问题在于如何提高采集站的瞬时动态范围，以便采集到尽可能多的高额分量。文章介绍了新型数据采集站的特点，指出了采用频谱整形方法改进瞬时动态范围的最大能力，并说明了在数据采集过程中对采样率以及前放增益的选择原则。
In this paper, based on the propagation characteristics of seismic waves in the strata, several important parameters related to high-resolution seismic data acquisition such as sampling rate, dynamic range, Put the gain, input noise, distortion, etc. were described, and analyzed the relationship between them. The core issue is how to increase the instantaneous dynamic range of the collection station in order to collect as much high-volume components as possible. This paper introduces the characteristics of the new data acquisition station, points out the maximum capability of using spectrum shaping method to improve instantaneous dynamic range, and explains the selection principle of sampling rate and forward gain during data acquisition.
