摘要
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。结果表明，蒸汽驱开发效果受它们的影响强烈。要确保项目在真正的蒸汽驱条件下运作，就必须使注汽速度、采注比和蒸汽干度在其临界值以上，否则开发效果急剧下降。国内外几个实例证明，其研究结果是正确的。
Through numerical modelling, this paper studies the process parameters of steam drive such as steam injection rate, production injection ratio, and steam quality. The result shows that the development result of steam drive is strongly influenced by them. To guarantee the project of steam drive works properly, it must be made sure that steam injection rate, production injection ratio and steam quality are above their critical value, otherwise the development result will drop rapidly. Several examples of domestic and abroad have proved that this point of view is correct.
