一种模块化地震勘探采集设备的设计和工作方式

YAN Wei.Block-based design of modular acquisition system

文中提供一种地球物理勘探开发地震仪器用的野外地震数据采集及记录与传输部件的工作方法。用于解决当前地震采集设备基本为专用设备配备专用电缆,仅在同一公司产品可实现部分混用,且设置繁琐,应用限制较大等问题。突破不同公司或不同类型的设备(有线、无线)无法混用、设备兼容性及利用率低下的现状。对比当前的各种采集设备,所述设计除了能够实现对现有地震勘探生产中常见的各种类型检波器(如电磁感应式模拟检波器、压电陶瓷式模拟检波器)等的数据接收外,还可根据地震采集的生产需求接入不同通讯模块以实现有线、无线、节点工作模式的转换。

This paper provides a working method of field seismic data acquisition,recording and transmission components for geophysical exploration and development seismic instruments.It is used to solve the problem that the current seismic acquisition equipment is basically equipped with special cables for special equipment,which can only be partially mixed in the same company's products,with cumbersome settings and large application restrictions.Different companies or different types of equipment(wired and wireless)cannot be mixed,and the equipment compatibility and utilization rate are low.Compared with the current acquisition equipment,the design can not only receive data from various types of geophones common in the existing seismic exploration production,such as electromagnetic induction analog geophones,piezoelectric ceramic analog geophones,but also connect different communication modules according to the production requirements of seismic acquisition to realize the conversion of wired,wireless and node working modes.
