Abstract

Изобретение относится к нефтедобывающей промышленности. Технический результат заключается в повышении продолжительности дозирования ингибитора. Контейнер состоит из корпуса (1), в стенках которого выполнены отверстия (2). Отверстия (2) выполнены в его верхней (3) и/или в средней (4) частях. Корпус (1) снабжен по торцам перфорированными нижней (5) и верхней (6) заглушками или перфорированной нижней и глухой (20) верхней заглушками. Внутри контейнера размещена по меньшей мере одна емкость (7), заполненная ингибитором 8 и снабженная по торцам глухими крышкой (9) и днищем (10). Емкость (7) выполнена перфорированной в радиальном направлении. Диаметр отверстий (11) составляет 1-7 мм. Емкости (7) не закреплены в корпусе (1) и образуют зазоры между их наружными стенками и внутренней поверхностью корпуса (1). Соотношение суммарной площади отверстий (2) к суммарной площади отверстий (11) во всех емкостях (7), находящихся внутри корпуса (1), составляет 1:(0,003-70) соответственно.The invention relates to the oil industry. The technical result is to increase the duration of the dosing of the inhibitor. The container consists of a body (1), in the walls of which holes (2) are made. Holes (2) are made in its upper (3) and / or in the middle (4) parts. The housing (1) is provided at the ends with perforated lower (5) and upper (6) plugs or perforated lower and deaf (20) upper plugs. Inside the container is placed at least one container (7), filled with inhibitor 8 and provided with a blind cover (9) and bottom (10) along the ends. The container (7) is perforated in the radial direction. The diameter of the holes (11) is 1-7 mm. The containers (7) are not fixed in the housing (1) and form gaps between their outer walls and the inner surface of the housing (1). The ratio of the total area of the holes (2) to the total area of the holes (11) in all containers (7) inside the housing (1) is 1: (0.003-70), respectively.
