NH 4BF 4 is an alkalescent inorganic salt in aqueous solution, and it can produce hydrofluoric acid through slow hydrolization, which makes it possible to acidify the matrix of sandstone reservoirs. The performances of acidizing fluid contains of NH 4BF 4 are studied, and the best formulation is optimized. The experimental results show that it has good characteristics of retarding and corrosion mitigation.
