FIELD: oil industry.
SUBSTANCE: group of inventions refers to multi-barrel drilling. Well system comprises a main wellbore and a lateral wellbore, the flow from the main wellbore to the interface node, deflector, located in the main wellbore in or near the coupling node, node of multi-barrel well coupling, and a first mechanical stiffener, located on the main well section, and a second mechanical stiffener, located on the section of the side borehole. Multi-hole bore interface unit is configured to pass within the main wellbore and includes a connector body, section of the main well, attached to the body of the connector in the receiving slot of the main well section, and a section of the side bore, attached to the connector housing in the receptacle of the borehole section. In this case, the main and side well sections are tubular constructions with a circular cross-section. Each of the first and second mechanical stiffeners has a generally D-shaped cross-section.
EFFECT: technical result is the strengthening of well sections with torsional and axial load during downhole.
