摘　　要：建立合适的供热系统运行优化策略是保证其优良运行效果的关键。某油区利用油田污水余热及当地地热资源作为供热热源,通过分析供热系统工艺流程,研究板式换热器和热泵机组的热交换过程,基于热量守恒原则,构建供热系统热交换计算模型,使其能够模拟供热系统实际运行情况。利用2015年供暖季运行数据,计算混合污水温度和板换换热系数变化对供热效果的影响,最后提出适宜的改进措施以提高供热系统运行效率,尽可能节约运行成本。Establish proper heating system operation optimization strategy is the key to ensure its good operation effect. A oilfield region utilizes sewage waste heat and local geothermal resources as the heating source. Based on the principle of heat conservation, through the analysis of heating system process, and the heat transfer process of plate heat exchanger and heat pump unit,we build the heating system heat transfer calculation model, to simulate heating system actual operation situation. The operating data in 2015 heating season, is used to calculate the effect of mixed sewage temperature and plate heat change coefficient on heating system,f inally we put forward appropriate improvement measures to improve heating system efficiency, and save operating cost as much as possible.
