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.
