Different flooding pattern and different injectionproductionratio are used for different reservoirs to maintain the reservoir at a reasonable level.
根据不同的油藏类型采用不同的注水方式以及不同的注采比，确保油层在某一压力下生产。

Through numerical modelling, this paper studies the process parameters of steam drive such as steam injection rate, productioninjectionratio, 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。
