A distributed low energy dynamic thermal management system for solid matter prevention and control in oil and gas transportation pipeline includes a pipeline data monitoring terminal, a current and an electric pulse control terminal, a land console, an electric heating terminal, a wiring flange, an oil and gas transportation pipeline, a valve structure. The system monitors the state of the pipeline in real time by the pipeline data monitoring terminal, and transmits the monitoring data to the current and electric pulse control terminal in real time, the current and electric pulse control terminal produces different thermal responses to the electric heating terminal according to the state in the tube, raises the temperature inside the tube by generating a continuous current, unblocks pipeline by generating high power electric pulse, so as to realize real-time monitoring and local temperature dynamic control of oil and gas transportation pipeline.

The present invention discloses an electric heating thermal management system for an oil and gas transportation pipeline based on renewable energy and COenergy storage. It transmits the feedback data value through a data collection device arranged in the pipeline to the early warning device by the control device. After analysis and processing, the early warning device can feed back the data value to the control device and the remote operation device in two modes. Different degrees of heating amount can be generated for the oil and gas transportation pipelines at different positions in different modes. Hierarchical and distributed management control for the oil and gas transportation pipelines can be targetedly conducted in unblocked, easily blocked and blocked positions of the oil and gas transportation pipeline. The present invention couples the renewable energy electricity supply device and the COenergy storage device.
