Release date: 2015-10-13 & Source: & Views: 1213
  • Conventional acidizing working solution is mainly composed of hydrochloric acid and hydrofluoric acid.  Because of the fast reaction with formation, they are consumed very quickly therefore only affect the formation in a short distance, reducing the efficiency of operation. With the addition of retarding agent in working fluid, the effective distance of the acid is prolonged. Retarding agent contains surfactant that is easily absorbed by formation, preventing reaction between acid and rock formation therefore serve the purpose of slow down the acidizing process.
