The invention discloses a remote monitoring management method and system for oil and gas production. The internet of things is mainly utilized, by means of sensing, radio frequency, communication and the like, production objects such as an oil and gas well, a metering room, an oil and gas station warehouse and an oil and gas pipe network are comprehensively sensed, production data and equipment state information are managed and controlled in a production command center and a production control center in a centralized mode, oil and gas production process management is supported, and timeliness and accuracy of oil and gas field production decision making are further improved. The system comprises a data acquisition and monitoring subsystem, a data transmission subsystem and a production management subsystem. The data acquisition and monitoring subsystem is arranged on an oil and gas production field, comprises sensors and RTUs or DCSs which are all installed on production equipment, and is used for automatically collecting state parameters of the production equipment and standardizing the state parameters, accuracy of the parameters, equipment identification and equipment attributes so that monitoring data can be formed. The data transmission subsystem is used for transmitting the monitoring data. The production management subsystem is used for conducting production state detection, analysis, diagnosis, prediction and early warning according to the monitoring data.
