所有瞬态测试解释方法都使用诊断图来识别井眼或裂缝存储变形、流动状态和其他参数。相关的诊断图在此类测试之间不可互换。这项工作的目的是为每种类型的瞬态测试明确定义适当的诊断图。
在整篇论文中，作者回顾了一些感兴趣的特定案例的恒定利率回撤解决方案，以及用于将累积数据与回撤解决方案相匹配的绘图函数。他们将审查扩展到短流动期后的累积或衰减分析的情况，并说明了短流动期和长流动期后的累积或衰减分析之间的差异。
All transient-test interpretation methods use diagnostic plots for the identification of wellbore or fracture storage distortion, flow regimes, and other parameters. The associated diagnostic plots are not interchangeable between such tests. The objective of this work is to clearly define the appropriate diagnostic plots for each type of transient test.
In the complete paper, the authors review constant-rate drawdown solutions for a few specific cases of interest and the plotting function used to match buildup data to the drawdown solutions. They extend their review to the cases of buildup or falloff analysis following short flow periods and illustrate the differences between analysis of buildup or falloffs following short and long flow periods.
