【摘要】 为解决我国传统油井计量方式存在的计量精度低、适用范围窄、检测及控制仪表多、成本高、劳动强度大、效率低等问题,设计开发了一套基于PLC的多油井自动计量监控系统,实现了多油井自动计量、远程传送数据、数据统计、历史查询以及远程监控等功能。现场应用结果表明:设计开发的多油井自动计量监控系统解决了传统分离器不能准确计量低液量、低含气、间歇出油油井的问题,实现了多油井多相连续计量以及远程监控的目标,简化了工艺流程,降低了劳动强度,提高了计量效率以及油井计量的准确度,为油田管理提供了准确可靠的计量数据。更多还原

【Abstract】 To solve the problems of low measurement accuracy,narrow scope of application,much more detection and control instruments,high cost,great labor intensity,low efficiency occurred in traditional oil well metering methods,a multi-well automation system of metering and monitoring based on PLC was developed,which realized the functions of automation metering,remote transmission of data,data statistics,history data querying and remote monitoring.It is shown by field application that the multi-well automatic metering and monitoring system can solve the problems exiting in the low liquid volume well,low gas and intermittent well which can’t be metered by traditional separator,and meets the need of multi-phase continuous measurement as well as remote monitoring.Additionally,it can also simplify the process,reduce labor intensity,improve accuracy and efficiency of metering,and supply reliable metering data for the oilfield servicer.更多还原
