摘要: The invention discloses a removing method for gas recovery well shaft aquo-complex blockage. After an acidic work solution is pumped into subjected to blockage, heating unit that calcium oxide coated with materials capable of being dissolved by the then put in. water at least comprising hydrochloric acid, metal corrosion inhibitor and hydrate inhibitor. According method, hydroxide generated in acute heat release caused process further reacts local part blockage heated, thus ice can be removed. No large-sized operation apparatus needed produced effectively concentrated so thermal efficiency greatly improved, removal time shortened; has advantages used agent dosage small; short; cost low; simple convenient; no new solid sediment processing process; condition caused.
