【摘要】：我国辽河油田自采用SAGD(Steam Assisted Gravity Drainage,简称SAGD蒸汽辅助重力泄油)技术开采稠油以来,地面井口采出液的温度大幅度提高,温度高达170-180℃,较高的井口采出液温度引起了较大的剩余热能。如何有效地回收和利用剩余的热能,降低生产运行费用,提高SAGD技术采油的整体经济效益,成为SAGD技术应用中急待研究的课题。针对这一问题,本文研究了余热综合利用的技术方案,列举了三个热能利用方案进行对比,优选出最佳的换热方案。对主要设备进行了选型分析,结合两种换热介质的物性特点,推荐了最适合本方案的换热器类型。对换热面积进行了计算,确定了换热器的换热面积和换热器台数。对全流程管线保温方案进行了优化设计,并通过计算,得出保温层经济厚度。并对整个技术方案的经济性及环保性进行了分析。
