摘　　要：辽河油田曙一区杜84块采用SAGD技术进行稠油开采,地面井口采出液温度高达170-180℃,从而获得较大的剩余热能。为了有效利用这部分余热,根据动力循环原理以及氟里昂循环发电系统的特点,设计研究了小型低温余热发电系统,并对系统中的主要换热元件(蒸发器、冷凝器)和汽轮机参数进行了热力计算,确定了蒸发器、冷凝器的结构参数及其电功率。研究结果对于基于朗肯循环的低温余热发电系统的工程设计具有一定的参考价值。SAGD technology used in Liaohe oil field area shu one district du 84 to exploit heavy oil,result in the temperature of wellhead produced fluid is up to 170—180 ℃,which led to a large waste heat.In order to effectively use this part of the heat,a small low-temperature waste heat power generation system is designed,based on the principle of power cycle and the characteristics of CFC cycle power generation system.Then the main heat exchanger components of the system（evaporator,condenser） and the turbine is thermodynamic calculated,and the structural parameters of evaporator and condenser and the electric power are determined.The results may be valuable for waste heat power generation system design based on the rankine cycle.
