In the vertical heterogeneous reservoir, the alcohol-induced salt grain could elevate the fluid flow resistance, increase the injection pressure and change the flow direction.

对于纵向非均质油藏，醇诱导后的盐结晶颗粒能使油流动阻力增大，压力上升，流动转向。

In the intergranular spaces of rocks, however, fluid must flow around and between grains in a tortuous path; this winding path causes a resistance to flow.

然而，在粒间孔发育的岩石中，流体必须在颗粒周围的曲折通道中流动；而这种曲折通道会对其流动产生阻力。

But for the life of the tube, flow rate, as well as fluid resistance, essentially no effect.

但对管子的寿命、流量、以及对流体的阻力，基本上没什么影响。
