摘要
依据?分析基本理论,对大庆油田某油气集输系统进行了用能薄弱环节分析与辨识。通过研究集输系统物流、?流分布情况,将系统划分为管网和转油站两个子系统,确定转油站子系统全年平均?效率为19. 41%,管网子系统全年平均?效率为72. 98%。根据计算结果对转油站子系统各用能单元?损分布情况进一步分析,得出外输泵及掺水泵?损占比较小,加热炉为主要用能损耗单元,其?损系数为84. 3%,应做为系统用能改进的主要单元。
According to the theory of exergy analysis, the energy use weak link of oil & gas gathering system in Daqing was analyzed and revealed. Through the logistics and exergy distribution analysis of oil transfer station system, the system was divided into two subsystems: the pipe network and the oil transfer station. And the annual average exergy efficiency of oil transfer station was 19.41 , and that of the pipe network was 72.98 . According to the calculation results, further analysis was made on the distribution of loss in each energy consumption unit of oil transfer station. The loss of oil pump and water pump was less. The heating furnace with coefficient of exergy loss of 84.3 was the main energy loss unit, and the main unit to enery utilization.
