Analyses and contrast shows that, the acid selected by experiment could improve the permeability nearby fracture surface and the fracture conductivity preferably.
常规压裂时，压裂液对裂缝壁面的污染越严重，裂缝壁面污染带的渗透率就越低，水力压裂能获得的增产倍比就越小；
For hydraulic fracturing, the damage to fracture surface is ever severe, the permeability of damage zone is ever low, and the production response of hydraulic fracturing is ever junior;
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.
