FIELD: construction.
SUBSTANCE: group of inventions relates to construction of wells for production of hydrocarbons. Method comprises drilling vertical branch at first preset depth to form wellbore. Vertical branch is widened at location of joint unit in vertical branch to form first connecting section. Binding material is introduced into first connecting section. Side branch is drilled at the first specified distance through the side wall of the first connecting section. Side branch is widened through the side wall of the first connecting section to form the second connecting section. Binding material is introduced into the first connecting section and the second connecting section to form a connection unit between the vertical branch and the side branch.
EFFECT: technical result is higher efficiency of construction of wells and reliability of device operation.
