On the interface where there are non-horizontal fractures, reflection coefficient of P-P wave has more extrema to show complexity and to fail to directly indicate fracture strike.
The influences given by horizontal fractures with different length and width and the different rate of fracture conductivity on the transient pressure are compared through calculation.
通过计算比较了不同长宽比的水平裂缝对瞬态压力的影响，比较不同裂缝传导率对瞬态压力的影响。

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