Compound for treating bottom-hole zone of oil bed has following components, mas.%: muriatic acid, 10.0-34.0; product from interaction of still residue in production of p-phenetidine or santoquin with organic solvent, 1.0-40.0; water, the balance. Compound can also additionally contain formaldehyde-bearing combination in amount of 0.05-10.0 mass%. Aforesaid compound allows for effective treating of bottom-hole zone due to reduced filtration resistance of bottom-hole zone of oil bed which is represented by carbonate or terrigenous reservoir with asphaltene-resin-paraffin depositions. EFFECT: higher efficiency. 8 cl, 2 tbl, 3 exi
