单井蒸汽驱生产动态的数值模拟及预测

Numerical Simulation And the Predlction of Single-Well Steam Flooding Production Change

在注蒸汽采油生产中，如何根据生产实际情况，预测油田生产动态，确定吞吐周期、注汽强度、油进排流速度，制定合理的开采方式，提高油田最终采收率，是稠油生产中十分重要的问题。本文有数值模拟方法对上述问题进行了探讨并经出了计算结果。

In steam flooding production, it is very important in heavy oil production to base on practical production the estimatiom of production change and the deternmination of cyclic steam phase, steam injection tate and oil well production velocity so that a rational production method can be obtained and oil recovery ratio increased. The parper employs numerical simulation method to discuss the problem and gives out the results of the calculation.
