The paper describes the multicomponent acid-base fluid CS-2 containing acid, surfactants, dissolvent and thermostable complexon-stabalizer of secondary sludge. The multicomponent fluid is recommended for acid treatment of producing wells with high temperature reservoirs containing asphalt, resin and paraffin deposits. The proposed solution combining hydrochloric acid and polyacrylic acid allows to achieve a 1,5 – 1,7-fold increase in production rate.

Key words: hydrodynamic properties; bottomhole zone; surfactants; multicomponent acid treatment fluid.
