摘　　要：在油田录井作业中,钻井现场环境恶劣,电磁干扰较大,为保证录井数据采集和传输的正确和可靠,在无线录井数据采集设计中采用先进的数字隔离器替代常用的光电隔离器。现场应用试验表明,该设计不仅降低了系统功耗,减少了PCB板面积,而且达到了高可靠性和高速传输的目的,完全满足录井工作的现场要求。The electromagnetic environment of well logging field is of much interference. In order to ensure the precision and the stability of data acquisition and transmission, digital isolator is applied to replace traditional op-electric isolator. Field experi- ments have proved that the design is suitable for the requirement of well logging, with better performance of reliability and high speed of data transmission. It also lowers the power consumption and the PCB size of the system.
