FIELD: mining.
SUBSTANCE: group of inventions refers to the extraction of oil, gas or minerals. Coupling assembly has at least one side section comprising a substantially Y-shaped tubular body formed by the wall and defining a hollow internal part, external surface, upper end by the wellbore and the main and the side ends lower by the wellbore, wherein the upper and lower ends by the wellbore and the lower and main ends by the wellbore are open relative to said internal part, first communication line segment extending between said upper by wellbore end and said lower by wellbore main end, and the second communication line segment extending between said upper by wellbore end and said lower by wellbore side end, main line connector disposed at said upper by wellbore end, a main section connector disposed at said lower by wellbore main end, side section connector disposed at said lower by wellbore side end. At that, said segments of the first and second communication lines are located completely outside of the said coupling assembly said internal part. At that, each of said mainline connector, said main section connector and said side section connector comprises the formed therein opening, which is hydraulically connected to said coupling assembly said internal part. At that, the said first communication line segment passes between said mainline connector and said main section connector, and said second communication line segment passes between said mainline connector and said side section connector.
EFFECT: monitoring and control over the bottomhole.
