新型SAGD采出液高效换热器现场试验研究
|
摘要
为提升蒸汽辅助重力泄油(Steam Assisted Gravity Drainage,SAGD)热采技术采出液余热利用效能,实现油田稠油热采节能降耗,设计并研发了一种新型高效换热器,该换热器基于分离式热管换热技术并采用多模块串联型式,弥补了常规管壳式和螺旋板式换热器在油田应用中易沉砂、易形成死油区、换热性能差的不足。通过现场样机试验,结果表明:该型换热器换热性能突出,在采出液流量大范围变动下能够稳定运行,显著提高了油田热采余热回收利用率。
To improve the waste-heat utilization efficiency of steam assisted gravity drainage(SAGD) thermal recovery technology and realize energy saving and consumption reduction in heavy oil thermal recovery, a new type of high efficiency heat exchanger is designed and developed. The heat exchanger is based on separate heat pipe technology and adopts multi-module series type, which makes up for the shortcomings of conventional shell-and-tube and spiral-plate heat exchangers in oilfield applications, such as easy to sink sand, easy to form dead oil zone and poor heat transfer performance. Through field prototype test, the results show that the heat exchanger has outstanding heat transfer performance, can operate stably under the large range of produced fluid flow, and significantly improves the utilization rate of waste heat recovery in oil thermal recovery.
