Abstract: Beidou positioning technology is used for monitoring and early warning of geological hazards along the oil and gas pipeline to minimize the threat and damage to oil and gas pipelines. The pipeline sections of Central China Product Pipeline under the jurisdiction of Jiangxi, Fuzhou and Hunan oil transportation departments were selected as research target areas, where the geological hazard risk points were automatically identified in high precision by domestic highresolution remote sensing image and corrected with manual visual interpretation method. The identification results can be used as the basic data for field investigation. The micrometric displacement monitoring device based on Beidou positioning technology was designed, and the slope displacement at geological hazard risk points was monitored in real time combined with high-precision positioning data processing technology. Based on the previous effective rainfall and forecast rainfall in research target areas, the geological hazard early warning model was built. Depending upon different oil transportation departments and stations, the model allows mobile early warning APP to push red, orange, yellow and blue early warning information at different levels and with different authorities. The research results are expected to provide some references for the intelligent application of real-time monitoring and early warning of geological hazards along the oil and gas pipeline.
