The utility model relates to an anti-theft device for an oil production pipeline. The anti-theft device comprises a plurality of sections of oil conveying pipe bodies with connected end parts, wherein the end parts of the oil conveying pipe bodies are connected by virtue of pipe joint sleeves; the pipe joint sleeves are internally provided with electromagnetic valve bodies; the oil conveying pipe bodies are provided with pressure sensors adjacent to the end parts connected with the pipe joint sleeves; the heads of the pressure sensors are arranged in oil conveying pipe holes of the oil conveying pipe bodies; the tails of the pressure sensors are provided with data connectors and anti-theft locks; the data connectors and the electromagnetic valve bodies are connected with data lines; the data lines are connected with a data bus; the data bus is connected with a monitoring chamber. The anti-theft device is sensitive in response; a pipeline oil leakage position can be discovered in time, and an oil conveying pipeline can be closed in time, so that great wastes of oil can be avoided, environment pollution is avoided, pipeline maintenance personnel is informed in time, external interference can be prevented, and the anti-theft device is stable in signal transmission and good in safety.
