The fhuoboric and hydrochloric acids are the main components of the retarded acid mixtures, which are less corrosive and suitable for use in the aeidizing operatiions in deep wells of low permeability sandstone reservoir. The reaction between the acids and the sandstone is significantly retarded at formation temperature c.a. 100℃. The acidizing test in laboratory and in situ are proved to be efficient and successful. The preparation and pumping of the retarded acid mixtures are convenient. The mixtures, however, must be modified to decrease their cost, before a new acidizing technique for well stimulation may be derloped.
