The invention discloses a cathode protection system for an oil and gas pipeline, and the system comprises a stray current detector which is used for detecting the stray current data of the pipeline; the environment monitoring module is used for collecting environment data of the pipeline; the cathode protection device is used for collecting reference potential data and power output data; the station control system is used for receiving the stray current data, the environment data, the reference potential data and the power supply output data which are remotely transmitted, and determining an ideal potential according to the data; and after the station control system determines the ideal potential, a corresponding control instruction is generated and sent to the cathode protection device, and the cathode protection device controls the output protection current according to the control instruction, so that the pipeline is at the ideal potential. Through data transmission between the cathode protection device and the station control system, the potential of the pipeline is effectively controlled at the given potential value of the station control system, the remote monitoring capability of the station control system on the cathode protection engineering of the pipeline is improved, and the corrosion rate of the pipeline is effectively reduced.
Description
technical field [0001] The invention relates to the technical field of pipeline protection, in particular to a cathodic protection system for oil and gas pipelines. Background technique [0002] In the cathodic protection process of the pipeline, the detection accuracy of the protection potential largely determines the monitoring ability of the protection effect. [0003] The problems existing in the current practical engineering are as follows: First, the potential detection method for cathodic protection of long-distance pipelines is mainly based on manual on-site inspection. Due to the long pipelines of long-distance oil and gas pipelines and the complicated areas they pass through, the detection process not only consumes manpower and material resources, but the manual inspection method is also affected by the working conditions, and it is impossible to judge the influence of stray current on the cathodic protection effect of the pipeline. The protection status cannot be...
