The invention discloses an oil and gas recovery monitoring device. The oil and gas recovery monitoring device comprises a man-machine operation module, a plurality of gas flow meters, a liquid flow meter, a plurality of temperature sensors, a plurality of pressure transmitters, a VOC concentration sensor, a refrigeration module, a video data acquisition module, a central processor, a physical model building module, a recovery method optimization module, a virtual sensor, a simulation analysis module, a drawing module, a regression calculation module and an oil and gas recovery condition evaluation module. With the oil and gas recovery monitoring device of the invention adopted, data automatic acquisition, analysis and automatic generation of records are realized, oil and gas recovery monitoring can be automated and informationized, and detection results are accurate; three-dimensional simulation display of oil and gas recovery to be monitored can be realized through a physical model, so that a user can more intuitively understand the condition of the oil and gas recovery to be monitored; and through the self-definition of the recovery method optimization module, the simulation analysis module and the virtual sensor, the simulation analysis of the physical model can be realized, and the formulation of various measures for different situations can be facilitated.
