摘要：

针对现代高性能声波测井仪器通常由若干个功能短节组成，仪器内部系统控制命令连接和局部高速数据传输接口乃至井下组合仪器系统之间的电气互联已经成为这类仪器和系统设计中需要解决的关键技术问题，采用现场串行总线CAN实现井下仪器之间的互联，仪器内部电子线路板之间和密封电子短节之间由专用串行命令总线完成主控制器对所有受控单元的控制连接，受控单元中的CPLD对命令进行译码并相应的设置参数，其传输速率为100kbps。板间高速串行数据传输接口由发送和接收控制器构成，全部采用CPLD实现，数据传输速率为5Mbps。串行数据传输方式连线简单可靠，便于隔离和屏蔽，并能达到所需的传输速率。基于该技术的声波测井仪器已经在油田生产现场完成了多口实验井和勘探井的测量，全面验证了所述串行数据传输应用的可行性和可靠性。

Abstract:

High performance acoustic logging tool consists of a number of parts,and its structure is complicated.Interface among tools,internal interface based on control commands and local high-speed data transmission interface are all key problem in technology in the design of the tool.Down-hole tools are connected each other by Controller Area Network.Special serial command bus completes interface between main controller and controlled units,and the control bus is applied to connect circuit boards and seal electronic cartridges.Complex programmable logic devices(CPLD) in controlled units decode receives commands and configure parameters accordingly.The rate of control bus is 100kbps.High-speed data transmission interface between boards is composed of sending controller and receiving controller,the two controllers are all accomplished by CPLD and data transmission rate is 5 Mbps.Serial data transmission mode is simple and reliable,it can be isolated and shielded easily,and the transmission rate can satisfy practical applications.Acoustic logging tools,based on the serial data transmission,were tested in several test wells and exploration wells of petroleum production field,and feasibility and reliability of serial data transfer are validated.

Key words: acoustic logging tool, serial bus, control command, CPLD, interface
