Supervisory control and data acquisition (SCADA) systems provide the modern, efficient and effective method of controlling and monitoring pipeline operation. Use of radio links utilizing VHF and UHF frequencies is an economical method to extend pipeline SGADA systems into remote areas, where no other communication facilities exist, to operate block valves and pump stations and to provide mobile radio communications for maintenance crews, This paper provides the design criteria for engineering VHF and UHF propagation paths for SCADA communications, and for mobile radio communications. The method is especially useful when line-of-sight clearance cannot be obtained above the surface of the earth for the propagation path.

监控和数据获取系统(SCADA)是监控管道运行的现代、高效和适宜的方法。采用甚高频和特高频无线电线路是将管道系统延伸到没有其他通信设施的遥远地区操纵截止阀、泵站以及向维修人员提供移动无线电通信的一种经济的方法。 本文提供了SCADA系统的VHF/UHF传播路径工程和无线电通信的设计标准。这种方法在传播路上对不能在地表面上获得视线余隙时特别有用。

In the light of the problems with imported offshore wellhead, such as being bulky and expensive

针对海上油田所用国外采油井口装置存在体积庞大笨重、价格昂贵以及与国产设施不配套和安装维护不便等问题,研制了HKY65—21型海上井口装置。这种井口装置主要由油管头总成、PHK平板闸阀、井口安全阀、截止阀、卡箍总成、小四通和节流器组成,具有体积小、重量轻、强度高、防腐耐磨、密封可靠和安装维护方便等优点。现场使用128套的实践表明,其各项技术性能指标均能满足海洋石油生产的要求,完全可以取代进口产品,经济效益可观。

高压(25MPa)天然气分配管线上对接焊缝很多,装有流量计、截止阀门等。总管排量(标准状态)每日100km3。利用声发射技术进行在线监测的结果表明,没有发现明显的材料缺陷活动的声发射信号,也没有发现任何微泄漏现象。根据应力集中部位的实测应变值,所计算得到的最高当量应力值为54.2MPa,因此,可以认为高压分配管线与截止阀具有一定的安全可靠性。经过三年运行,证明这一结果是可靠的。
