摘要
本文采用数值模拟方法研究了双重介质注水井关井后的压降曲线特征,分析了渗吸常数和渗吸半衰期对压降曲线的影响状况,最后,得出了这类试井曲线的分析方法。
This paper has studied the characteristics of pressure fall-off curves for water injection well in double media reservoir by using the numerical simulation method, analyzed the influence of imbibition constant and imbibition halflife on pressure fall-off curves, and finally suggested a method of analysis of those curves.
