Abstract

The invention relates to oil industry. The technical result is increased inhibitor dosage duration. A container consists of a body 1, in which walls there are perforated holes 2. The holes 2 are made in its upper 3 and/or middle 4 parts. The body 1 is provided with perforated bottom 5 and upper 6 plugs at the ends, or perforated lower and blind 20 upper plugs. At least one vessel 7 is placed inside the container, filled with inhibitor 8 and provided at the ends with a blind cover 9 and a bottom 10. The vessel 7 is perforated in radial direction. The diameter of holes 11 is 1-7 mm. The vessels 7 are not fixed in the body 1 and form gaps between their outer walls and an inner surface of the body 1. The ratio of the total area of the holes 2 to the total area of the holes 11 in all vessels 7 contained within the body 1, is 1 to (0.003-70), respectively.
