美国SEG53届年会于1983年9月11日至15日在拉斯韦加斯市召开。我国地矿部代表在参加该年会后又访问了美国若干物探公司和大学等单位。以下对国外石油地震勘探方面的主要进展作一简单介绍。一、地震仪器的发展本届SEG年会上除继续展出了好几种多道遥测数字地震仪外,还展出了一批配备有微处理机和大容量存贮器的数字地震仪。这种地震仪具有相当强的计算机功能,它一方面可以对野外资料采集过程实现自动监督与控制,另一方面还能对资料进行现场处理。
The United States SEG 53 Annual Meeting was held in Las Vegas from September 11 to 15, 1983. After participating in the annual meeting, representatives of China’s Mines and Minerals visited several geophysical companies and universities in the United States. The following is a brief introduction of the major progress in the foreign oil seismic exploration. I. Development of Seismographs In addition to continuing to exhibit several multi-channel telemetry digital seismographs at this SEG annual conference, a number of digital seismographs equipped with microprocessors and large-capacity memories are on display. This seismometer has quite a strong computer function, it can automatically supervise and control the field data acquisition process on the one hand, on the other hand can also be on-site processing of the data.
