海洋可控源电磁发射系统状态信息采集技术研究

Research on the state information acquisition technology of marine controlled source electromagnetic transmitter system

海洋可控源电磁发射系统是海洋可控源电磁勘探的重要组成部分,而状态信息采集是其不可缺少的部分,尤其是在高压、高温和强干扰的条件下,状态信息采集对仪器设备的可靠稳定运行起着不可估量的作用。本着简单、易用、可靠和高安全系数的原则,利用CAN总线、串口、光纤和无线网络等技术,对新一代的海洋可控源电磁发射系统状态采集技术进行了设计和实现。海上试验表明,所研究的状态采集技术方案简单易用,稳定可靠,满足了海洋可控源电磁发射系统的苛刻需求,已实际应用于我国南海可燃冰勘探生产任务当中。

State information acquisition is an indispensable part for MCSEM(marine controllable source electromagnetic)transmitter system which is important for MCSEM exploration.Especially under the conditions of high voltage,high temperature and strong interference,it plays an inestimable role in the reliable and stable operation of the instrument.Based on the principles of simplicity,ease of use,reliability and high safety factor,the state acquisition technology for the new generation of MCSEM transmitter system is designed and implemented by using the technology of CAN bus,serial port,optical fiber and wireless network.Test shows that the technical scheme of state acquisition is simple,stable and reliable.It has meet the harsh requirements of MCSEM transmitter system and has been applied to the exploration of nature gas hydrate in South China Sea.
