Therefore, the impact of starting pressuregradient must be considered when analyzing the productivity of vertical fracture well in low permeability reservoir.
因此,在进行低渗透油藏垂直裂缝井产能分析时,必须考虑启动压力梯度的影响。

The compacting density, bending strength, fracture toughness and rigidity value of the synthesis can be prepared to be applicable gradient material structure under suitable pressure and temperature.
在适当的压力、温度环境下合成致密度、弯曲强度、断裂韧性、硬度值可满足实际应用背景的梯度夹层。
