FIELD: well drilling, particularly, deformed multiwell templates and methods of drilling many underground wells with the help of said templates located inside borehole of underground well and expanding in well drilling. SUBSTANCE: template is located in well and expands, and at least one underground borehole is drilled through said template. At least one part of template is deformed and may be symmetrical or asymmetric in deformed or expanded form. Invention makes it possible to drill and equip many wells from standard size bore with increased hydrocarbon recovery efficiency and higher reliability of hydraulic seal of template. EFFECT: higher efficiency. 17 cl, 28 dwg
