1、（效率管理）高含水后期 油气集输系统效率及能耗 计算分析 摘 要 油田既是产能大户，也是耗能大户。油田地面工程耗能在整个油田耗能中占 有较大比例，而原油集输系统又是油田地面工程的主要耗能部分。目前国内外对 高含水后期油气集输系统效率及能耗分析的研究报道比较少，因此，急需进行大 量的工作弥补这方面的不足。 本文依据大庆采油四厂杏十联地区原油集输系统冬季掺水加热期运行数据测 试结果，对该地区原油集输系统各部分进行了效率及能耗计算。论文主要包括如 下几部分：联合站效率及能耗计算、转油站效率及能耗计算、集输管网效率及能 耗计算以及整个原油集输系统效率及能耗计算。在计算的基础上分析了集输系统 各部分的用
2、能状况，找出了该地区原油集输系统用能的薄弱环节，通过计算分析， 该系统热耗占总能耗的 95.76%，因此降低热耗是提高能量利用率的关键。转油 站能量损耗占系统总能损的 75.62%，是整个系统中能损最大的部分。提出了节 能改造方案，并预测了该系统的节能潜力。预测经过节能改造后，该地区油气集 输系统每年节电 1.878106kWh，每年节气 2.11106m3，年节约能量 8.61107MJ。 关键词：油气集输系统；效率；改造；能耗；计算 Abstract The oil field is a large energy producer, as well as a large energy co
