摘　　要：塔式光热系统可利用太阳能为油田提供零碳蒸汽,但受光资源影响大,供汽存在波动性,影响供汽管网及用汽井口蒸汽稳定性。设计一种新型联合供汽系统,通过将光热与锅炉联合接入注汽管网,保证供汽稳定性。针对不同管网类型以及光热接入位置,分析了光热蒸汽波动时管网的稳态及瞬态工况。结果表明:相比环形管网,光热流量变化对树形管网井口流量影响较大;光热制汽接入管网母管位置时,光热波动对管网稳定性影响明显小于接入管网远端位置;光热与锅炉联合运行,可以平抑光热波动带来的管网波动问题。The tower concentrated solar system can provide zero-carbon superheated steam for the oil field. However the solar resources are changing with time and weather condition, which may lead to fluctuation of steam flow. A new combined steam supply system network is designed, in witch the stability of steam can be guaranteed by integrating solar steam with gas-fired steam boiler to the network. Based on different types of pipeline networks and access location of solar steam, the steady-state and transient operating conditions of pipeline network during solar steam fluctuations are analyzed. Compare with annular network, oil well inlet steam flow of tree-type network has greater fluctuation when solar steam is changing. When solar steam is connected to the main pipe of network, the oil well inlet steam fluctuation from the influence of solar steam is obviously less than that at the remote end of the network. By combining the solar steam and gas-fired boiler steam, the steam fluctuation form the influence of solar steam can be significantly restrained.
