Abstract:

The solubilities of gypsum in carbonate rock acidizing process are measured in the experiments at different temperature and in different media. The change law of gypsum solubilities is discussed and the method of increasing the solubility of gypsum is presented by adding CaCl2 in the acidizing process to produce plasma effect.

Key words: Gypsum, Carbonate rock, Acidulate, Solubility
