摘要
为了满足地球物理勘探开发技术的发展需求,地震数据采集系统一如既往地朝着大道数的方向发展。随着采集道数(节点)的成倍增加,野外勘探作业产生的海量数据的回收和管理正面临空前的挑战。本文从目前地震仪器结构分析出发,描述了地球物理勘探开发中实时地震数据采集的定义,实时地震数据采集对各种类型地震仪器的基本要求。并且阐述了提高地震数据采集系统实时性的方法和途径。提出了地震数据采集的实时性将成为衡量或评估地震数据采集系统性能的一个重要的性能指标。
In order to meet the demand for the development of geophysical exploration and development technology, seis- mic data acquisition system, as always, must to increase acquisition channel numbers. Therefore we would face with an unprecedented challenge on receiving and management for mass data came from seismic exploration service. Based on the structure analysis of current seismic data acquisition system, this paper introduced the meaning of real time seismic data acquisition, and described the basic requirement of the real-time performance for seismic data acquisition systems, and also provided how to enhance the real-time performance of seismic data system. In the meantime on this article we mentioned that the performance of seismic data acquisition in real time will be one of the important i- tem of the specifications that be use to evaluate the seismic data acquisition system performance.
