RD-04 multi-hydrogen acid

The multi-hydrogen acid (MHA), as compared with routine mud acid system, is of higher velocity slowing and absorbing capacity, especially in the initial state of reaction, the velocity of which can be 0% of other acid system. This system’s corrosion rate to quartz is much higher than mud acid and fluoboric acid, and reduces the reaction velocity involving minerals in the clay. It also preserves the moist in the stratum and do not fetters oil-gas seepage flow. Its acidification of sandstone stratum is better than routine   mud acid and fluoboric acid systems for its spanning effective distance without secondary sediment.
