【摘要】 要适应三维勘探对高分辨率和大道数的要求,早期生产的I/O SYSTEM TWO仪器就必须进行系统扩容。因该仪器的地面设备具有良好的兼容性,所以扩容的重点和难点在于仪器的主机部分。本文介绍了I/O SYSTEMTWO在三维施工中有关硬件联机、道能力扩展及磁带机升级等方面的注意事项。更多还原

【Abstract】 In order to meet the requirements of 3D seismic exploration for high resolution and large number of channels, I/O SYSTEM TWO should be upgraded. Because I/O System Two field unit of I/O SYSTEM TWO have good compatibility, so the focus is on the upgrading of central recording system. This paper points out something needing attention about the hardware online-capability extension and TTM upgrading.更多还原
