Strong scouring and flowback capacities.
The self-sealing function of formed acid can improve the acid washing efficiency with uniform scouring.
Combination of acid pickling and sand control 
Completely remove the blockage of drilling fluid filter cakes and the medium size of solid particles at the bottom;
