ES-2420反射地震仪是美国EG & G Geometrics公司研制成功的一种新型的带微处理机的高性能反射地震仪。该仪器设计新颖、结构独特、工作稳定、性能较好,适用于浅层或中深层地震勘探。近几年来,我国石油、地质、煤炭等部门,先后引进数十台这种仪器。本文介绍ES-2420反射地震仪的基本工作原理,可供从事地震勘探工作的同志参考。
ES-2420 Reflective Seismograph is a new type of high-performance reflective seismograph with microprocessor developed by EG & G Geometrics Company in the United States. The novel design of the instrument, unique structure, stable work, better performance, suitable for shallow or medium deep seismic exploration. In recent years, China’s petroleum, geology, coal and other departments have successively introduced dozens of such instruments. This article introduces the basic working principle of ES-2420 reflection seismograph, which can be used as a reference for people engaged in seismic exploration.
