In addition, this amended method can also be used to diagnosis whether the hot loss effect seriously affects the availability of pressurefall off test.
此外,修正方法还能判断热损效应是否严重地影响压力降试井方法的可用性。

Based on these, the new method that pressure build-up curve associated with pressurefall-off curve to determining the productivity of gas well is proposed.
Basing on the laws, the paper applies the pressure-flow distinguishing method into the pipeline leak detection, and through using the method of detecting the time of pressurefall.
