查询词典 barrier

Inadequateness leads to thin artificial barrier, which cannot form a low permeable or impermeable artificial barrier, which just cause lower differential pressure, this cannot control the extension on the height effectively.Moreover, because the artificial barrier cannot achieve the function of the height controlled, finally make the projection less efficiency, even could be defeated comes to an end.

过少则人工隔层过薄，不能形成一个低渗透或不渗透的人工遮挡层，只能在裂缝垂直方向上形成较小的压降，从而不能更有效的遏制裂缝在纵向上延伸；另外，由于遮挡层起不到控制缝高的作用，降低了压裂效率，最终施工效果不明显，甚至会以失败告终。
