Abstract: A rotating apparatus and a method for measuring acid-rock reaction characteristics in high temperature and pressure are provided. The apparatus for measuring the acid-rock reaction characteristics includes: a first reactor configured to react a rock disk with an acid; a second reactor configured to produce a spent acid through reaction of a rock with an acid aqueous solution, and to introduce the spent acid into the first reactor; and a sample extractor configured to extract a predetermined amount of acid reacting with the rock disk in the first reactor. Accordingly, the rock disk is rotated in the acid at high temperature and pressure in consideration of the reaction characteristics of the rock dissolved in the acid, and then a predetermined amount of acid reacting the rock is obtained with time. In addition, a flow of an acid in a real reservoir can be implemented by producing a spent acid and then reacting the rock disk with the spent acid at a reservoir condition.
