Hence, it is a very important problem to perform well test, evaluate the deliverability of the fractured horizontal well, and optimize the fracture parameters.

因此，对水平井压裂后的试井和产能评价，以及压裂水平井的裂缝参数优化是一个十分重要的问题。

When studying the conventional deliverability analysis of the tight gas reservoir, the tight gas reservoir will always need long test time to stabilize due to its low permeability.

对致密气藏进行常规产能分析时，由于渗透率极低，要达到稳定通常需要很长的测试时间。
