Through numerical modelling, this paper studies the process parameters of steam drive such as steam injection rate, production injection ratio, and steam quality.
利用数值模拟方法对蒸汽驱中注汽速度、采注比和蒸汽干度等工艺参数进行了研究。
Under the production condition of steam injection, the energy ratio can reach 7.0.
在注入蒸汽开采初始条件下，能量效率可以达到7.0。
It can also be used to calculate recoverable reserves according to the extreme oil steam ratio in this period.
