摘要
本文根据不同的计算蒸汽驱采收率方法所应用参数的不同，将蒸汽驱采收率的计算方法分为两类：一是以油藏基本特征参数为依据，计算的是在蒸汽驱合理操作条件下应该取得的采收率，这类方法称为静态法；二是以蒸汽驱开发动态所表现出来的规律为依据，计算的是在现行的操作条件下可能取得的采收率，这类方法称为动态法。通过分析这两类方法计算的蒸汽驱采收率的内在含义指出，在油藏描述准确的条件下，两类方法计算的蒸汽驱采收率的差值可以反映出实际操作条件的合理与否。差位越大，说明操作条件越偏离真正的蒸汽驱操作条件，必须尽快调整和改善汽驱参件，以便使蒸汽驱取得应有的效果。
Based on the different parameters used in different calculations of steam drive recovery factor, the calculation methods of steam drive recovery factor are divided into two types in this paper. One is on the base of main characteristic parameters of the reservoir to calculate the deserved recovery factor under the condition of rational operation of steam drive which is called static method. The other is based on the steam flooding performance to calculate the probable recovery factor under the current operation condition which is called dynamic method. By comparing the steam drive recovery factors calculated by these two types of method and analyzing their implications, it is concluded that under the condition of correct rescrvoir description,the difference of the steam drive recovery factors calculated by these two types of method can reflect whether the operation condition is rational or not. The bigger the difference, the poor the operation condition of steam drive. Therefore, it is necessary to adjust and improve the operation condition ot steam drive in order to obtain the deserved development result of steam drive.
