酸液在裂缝壁面上进一步刻蚀形成较深的沟槽，即使在高的闭合应力条件下，酸蚀裂缝也能保持较高的导流能力，从而改善酸压效果。
Moreover, the acid will further etch the fracture face and create deeper channels which leads to high fracture conductivity and better treatment effect even under high closure stress.
经分析对比表明，通过实验筛选出的合理的酸液配方能较好的改善裂缝壁面附近地层的渗透率和支撑裂缝的导流能力。
Analyses and contrast shows that, the acid selected by experiment could improve the permeability nearby fracture surface and the fracture conductivity preferably.
