Evaluation method of acid-sensitive sandstone reservoir matrix deep acidification retarding liquid

The invention provides an evaluation method of an acid-sensitive sandstone reservoir matrix deep acidification retarding liquid. The evaluation method comprises the following steps: acquiring information and parameters of minerals influencing acidized rocks; establishing a model for changing the acidification and acid etching quality of the rock core along with time; establishing the change relation of the single mineral and the content of the rock along with time; establishing an acid-rock reaction speed formula of the single mineral component of the key rock in the acidizing fluid; and comprehensively comparing and analyzing the acid-sensitive sandstone reservoir matrix deep acidification retarding liquid, and carrying out applicability evaluation. According to the evaluation method for the acid-sensitive sandstone reservoir matrix deep acidification retarded fluid, a targeted basis can be provided for model selection and proportioning of the retarded acidification fluid, so that the acidification success r
