Long-Distance Oil Pipeline's Running Process and Control Operations

Long-distance oil pipeline controlled the hydraulic and thermal system through the SCADA system. Hydraulic controls included a stable and non-stable condition pressure control while thermal control mainly ensured that the downstream pitted oil temperature was 3°C higher than the freezing point. Major running processes of crude oil pipeline contained integrated heat treatment, heat treatment heating and normal atmospheric temperature transportation technology. Large contaminated transport processes might be applied to many kinds of oil transport to reduce the risk of pipeline operation, so as to reduce human operation. A water hammer protection program was an automatic protection procedure used mainly in the abnormal working conditions of the pipeline, which had been applied to almost all long-distance oil pipelines. Pipeline running operation included operation under normal conditions. abnormal conditions, and emergency conditions. The dispatchers needed timely and effective operation to ensure that the pipeline runs safely under abnormal and emergency conditions.
