Well logging is one of the most important core technology in oil-gas exploration. In the well logging operation, the high reliability of data acquisition directly related to the evaluation and analysis of oil-gas reservoir, so it is very important. In this paper, a kind of comprehensive logging system with hot standby technology was designed to aim at the high reliability of data acquisition. Unlike the common hot standby mode with different software between master server and slave server, in this system, master server and slave server are equipotent. It confirmed the identities of master server and slave server according to start-up sequence, and it also has the following functions: synchronous renewal of the configuration files, synchronous storage of data, heartbeat detection, fault diagnosis and server switch. Field application proved that this system can satisfy the needs of comprehensive logging operation. In this paper design principles of software system and work flow was described.
