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。

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

目前对水力压裂效果评价最有效的方法是压力恢复试井。

Buildup test is now recognized to be the most effective method for evaluation of hydraulic fracturing performance.

本方法的使用，改变了过去对压裂效果评价的不合理性。

Unreasonable evaluation of fracturing result is improved with using the technique.
