A low-energy dynamic thermal management system for the prevention and control of solids in distributed oil and gas transportation pipelines belongs to the technical field of fluid safety assurance for oil and gas transportation pipelines. Including pipeline data monitoring terminal, current and electric pulse control terminal, land console, electric heating terminal, wiring flange, oil and gas transportation pipeline, valve structure. The system monitors the state in the pipe in real time through the pipeline data monitoring end, and transmits the monitoring data to the current and electric pulse control end in real time. The current and electric pulse control end generates different thermal responses to the electric heating end according to the state in the pipe. The temperature inside the pipe can be deblocked by generating high-power electric pulses to realize real-time monitoring of oil and gas pipelines and dynamic control of local temperature. The invention can greatly reduce the electricity cost for long-term maintenance of pipeline temperature, avoid or greatly reduce the usage of hydrate inhibitors, wax deposition antipolymerization agents, etc., reduce the cost of safety management of oil and gas transportation pipelines, and effectively improve the efficiency of plugging removal. Strong applicability.
Description
technical field [0001] The invention belongs to the technical field of fluid safety assurance for oil and gas transportation pipelines, and relates to a low-energy dynamic thermal management system for preventing and controlling solids in oil and gas transportation pipelines. Background technique [0002] (1) Background of solids generation in oil and gas transportation pipelines: [0003] During oil and gas extraction and transportation, due to high pressure and low temperature conditions, solids such as gas hydrates and wax deposits are easily formed to block pipelines, especially at pipeline valves or dead pipes used for maintenance services. [0004] At present, there are two main methods to prevent hydrate blockage of oil and gas transportation pipelines: heating method and adding inhibitor method. Among them, the heating method refers to heating the clogged position so that the temperature is higher than the hydrate phase equilibrium temperature under the system press...
