FIELD: oil and gas production.
SUBSTANCE: system of well completion consists of connector for side branch, of guiding device and of device of deadlock. Also, the connector of the side branch corresponds to a nipple with the first plug secured in the guiding device. The guiding device is made as a sub with the second plug, when assembled passing through the nipple. The connector includes a pump unit with devices of deadlock made in form of yokes and feed pipes with a receiver, between them there is installed an extension.
EFFECT: reduced weight-dimension characteristics and expanded functionality of system for well completion due to modularity of structure.
