一、概述随着油田建设事业的不断发展,油田生产自动化水平也越来越高。要适应这种变化,计量及自控仪表的种类、准确度、功能、自动化程度和管理工作都必须相应提高。但是近些年仪表生产厂家很少提供原理图或故障检查的详细说明资料,一般只提供一个简单的使用说明,这样一旦计量及自控仪表发生故障,很难立即查出故障并予以排除,若与厂家联系修理,则存在时 First, an overview With the continuous development of oilfield construction, oil production automation level is also getting higher and higher. To adapt to this change, the type, accuracy, function, degree of automation, and management of gauges and self-contained gauges must all be increased accordingly. However, in recent years, instrument manufacturers rarely provide detailed description of the schematic or troubleshooting information, generally provide only a simple instructions, so once the measurement and self-control instrument fails, it is difficult to immediately identify and eliminate the fault, and if Manufacturers contact repair, then there
