FIELD: oil and gas industry.
SUBSTANCE: method of bottom-hole formation zone stabilising includes introduction to the well of carboxymethyl cellulose aqueous solution with aluminium cuttings and finely divided incurred rubber with the following ratio of components: 1.5 wt % carboxymethyl cellulose, 14.5 wt % of aluminium cuttings, 11.6 wt % of finely divided incurred rubber, 69.2 wt % of water. At that during makeup of carboxymethyl cellulose aqueous solution 3.2 wt % of copper acetate is introduced additionally. Hydrochloric acid is pumped through the solution with the weight part ratio of aluminium and hydrochloric acid is 25.0:75.0% respectively. The solution is withheld in time.
EFFECT: higher efficiency of the bottomhole zone stabilising.
