FIELD: oil-and-gas production. ^ SUBSTANCE: invention related to boring machines for direct running of upward boreholes of rocks with different strength. Boring machines for upwards boreholes running, includes driver unit with rock cutting tools, caterpillar trays with drive and unit for it thrust, installed with possibility to interact with floating lever mechanisms, connected to caterpillar trays and includes devices for caterpillar trays declination - adjustable rods with their length adjustment mechanisms. Boring machine equipped with reactive rods, connected with caterpillar trays thrust unit and one of the floating lever mechanism, located at side opposite to drive working unit. One of the floating lever mechanisms rods executed as the caterpillar trays declination device - adjustable rods, located at drive working unit side. Adjustable rods length adjustment mechanisms executed with adjustment fixing device. Drive working unit can be changeable: planet -dynamical or planet cutting tool. ^ EFFECT: boring machine controllability increase in because of its more direct motion along the well axis desired routing. ^ 3 cl, 1 dwg |
