The energy consumption cost usually accounts for 30% of the oil pipeline operational costs.And with the increasing efforts of national environmental protection and carbon emission control, energy consumption cost has become one of the key points of reducing cost and increasing enterprise benefit.Conventional optimization only considers the optimization of thermal and power consumption,and both of them are considered independently.Considering the significant changes in the oil and gas market and the national electrical reform policy in recent years,if the thermal and power consumption are converted into cost, the optimal operating conditions of energy consumption and cost will be different.Taking a long-distance insulation pipeline as an example, the differences between the optimum energy-saving operation condition and the lowest energy consumption cost operator are cleared,and the potential optimization space of energy consumption cost is tapped out.The results show that there is a big difference between the energy-saving operation mode and the lowest operation mode of energy-consuming cost.The energy-consuming cost can be effectively reduced by implementing oil and gas burning conversion and reasonable choosing electricity bill settlement method.This study provides guidance for reducing operation cost and improving economic benefit of hot oil pipeline.
