多级变流量直接综合试井分析的新方法

A new method of directly comprehensive well test interpretation of mutiple variable flow rate

多级变流量的试井资料难于解释,在有关变流量的试井分析方法中,应用基于Tiab思想的直接综合试井分析方法就比较简便。以常用的完整变流量史的叠加等效时间形式的压力函数为基础,利用叠加原理,提出了一种新的多级变流量直接综合试井分析方法,并开发了相应的试井分析软件。以1口典型的生产井多级变流量测试数据验证了该方法的正确性,其分析结果与常规的图版拟合方法所得结果一致。

It is very difficult to interpret well test data of multiple variable flow rate. In the methods of well test interpretation of variable flow rate, the method of directly comprehensive well test interpretation based on Tiab' s thought is relatively simple. A new method of directly comprehensive well test interpretation of multiple variable flow rate is proposed based on the common pressure function of stacking equivalent time in full flow rate history and superpositon principle, and the relevant software is developed. Applicability of this technique is illustrated by typical multiple variable flow-rate data of a producing well, and the result indicates that the new method is identical with that of the conventional type matching curve.
