FIELD: construction and running of multiple face holes for the purposes of search, prospecting and development of hydrocarbon fields. SUBSTANCE: branches are drilled, fixed and tools are sunk into them along tangent line to curvilinear trajectory of main shaft in direction of hole target with the aid of conductor which upper part is fitted with fixing aids for depth and circumference and which lower part is provided with inclined chute and window installed by means of inclinometer in plane of maximal zenith angle equal in sum to inclination angle of chute and zenith angle of main shaft. EFFECT: increased efficiency of construction and running of hole thanks to prevention of drilling troubles and to provision for selective hitting of proper branch with devices and tools with execution of jobs in prospecting and development of fields. 2 dwg
