钻井局域网实时监控设备研发

为实现钻井指挥部对各钻井站点钻采工艺的远程监控，在前期钻井工艺参数自动实时监测的单机研发基础上,本文应用TIA portal软件进行主站从站组网监控研究，实验设备用Siemens1200PLC做主控机，用Siemens200PLC做从站控制机监控钻采现场工艺参数，通过主控机与各从站点组态，实现主控机对从站主从控制。装机后在钻采现场进行了无线网传输实验，实验结果表明:应用互联网通信技术解决无线网断点续传问题，能够实现了钻采实时监控数据短距离传输。

Research and development of real-time monitoring equipmentfor drilling local area network

In order to realize remote monitoring of the drilling process at each drilling station by the drilling headquarters, on the basis of the single station for automatic real-time drilling monitoring developed in the early stage, TIA portal software was applied to develope the master-slave station for drilling monitoring with Siemens1200PLC used as the master control equipment, and Siemens200PLC as the slave control equipment to monitor the drilling parameters at each drilling station. Master-slave controlling is realized through the configuration of the master control equipment and slave control equipment at each station. Internet was used to test transmission after the master-slave station was set up, and the results showed that internet can provide continuous transmission from breakpoint and short-distance transmission of real-time monitoring data on drilling.
