| 摘要 |
The invention relates to equipment for the petroleum industry, in particular to autonomous devices for supplying a reagent to a well and metering said reagent into extracted liquid. The technical result consists in multiply increasing the capacity of a device without increasing the weight of said device in order to increase the length of time for which reagent is metered into the well fluid. The device consists of cylindrical containers (1) filled with a reagent and having end stoppers (2) and (3), which are connected by connecting pipes (10), and metering devices (9), which are in communication with mixing chambers (13) and are hydraulically connected to the well. A shaft (5) with threaded ends (6) screwed into axial threaded openings (4) in the end stoppers (2) and (3) is mounted in each container. The metering device (9) is formed in the upper part of the shaft (5) in the form of an axial channel (7) and radial openings (8) communicating with said channel, while the mixing chambers (13) are arranged inside the connecting pipe (10).
