辽河油田是我国最大的稠油高凝油生产基地,稠油主要采用蒸汽吞吐和蒸汽驱的开采方式。稠油热采在蒸汽吞吐末期一般转蒸汽驱开发,蒸汽驱现场往往存在一台锅炉同时向2-3口井注汽,或多台注汽锅炉为整个注汽管网供汽的现象,存在干度分配的偏差,为此提出以下一种新的等干度分配技术,保证了一台或多台注汽锅炉在同时注多口井时的注汽干度相同、注汽速度相同。
Liaohe Oilfield is China’s largest heavy oil production base of high pour point, heavy oil mainly steam huff and steam flooding mining methods. Heavy oil thermal recovery in the steam end of the general turn steam flooding development, steam flooding scene often there is a steam injection to 2-3 wells at the same time, or more steam injection steam boiler for the entire network of steam supply phenomenon, there To this end, the following new dryness distribution technology is proposed to ensure that the steam injection rate of one or more steam injection boilers is the same at the same time when injecting multiple wells at the same time.
