摘　　要：SAGD作为超稠油蒸汽吞吐开发中后期接替技术,其主要生产特点是高温高压,伴随着大量的热能产生,充分利用产生的热能可节省更多的燃料消耗。近年来,辽河油田致力于SAGD开发热能综合利用研究,通过锅炉及流程改造,联合站加装换热装置,着力提高SAGD热效率,使注汽高温分离水和高温产出液的热能得到充分有效利用,预计年减少天然气用量4004×10~4m^3,减少污水外排347×10~4m^3,实现了污水零外排,节约清水252×10~4t。在节能减排和降本增效方面见到了突出成效,为进一步提高油田效益探索出一条有效的途径。As the replacement technology in the mid and late period of steam huff and puff development for super heavy oil,SAGD is characterized by high temperature,high pressure and a lot of heat energy,so making full use of produced heat energy can reduce more fuel consumption.In recent years,Liaohe Oilfield has been committed to comprehensive utilization of heat energy in SAGD development.Through reforming boilers and processes,adding heat exchange devices to united stations,SAGD thermal efficiency increases and the heat energy of hightemperature separation water and produced liquid of steam injection are fully used.By doing so,it is estimated that annual consumption of natural gas can be reduced by 4004×10~4m^3,and sewage disposition can be reduced by 347×10~4m^3,which achieves zero sewage disposition and saves 252×10~4t of clean water.The outstanding achievement in energy conservation,emission reduction,cost reduction and efficiency improvement can be seen,and it provides an effective way to further improve benefits for the oilfield.
