FIELD: oil and gas industry.
SUBSTANCE: well system comprises an inclined wedge positioned in the main wellbore and determining the first channel having a predetermined diameter and connected to the bottom part of the main bore, and the second channel connected to the lateral bore, and a bullnose comprising a housing and a bullnose cap positioned at the distal end of the housing. The bullnose cap can be actuated in the interval between default configuration, when the bullnose cap has the first diameter, and acutated configuration, when the bullnose cap has the second diameter different from the first diameter. The inclined wedge is arranged so as to direct the bullnose to one of the following: lateral bore or bottom part of the main bore, based on comparison of bullnose cap diameter and predetermined diameter.
EFFECT: errorless direction of assembly with a rounded head to the main wellbore or to the lateral wellbore.
