Description

котором необходимо расширение ствола. При прокачивании жидкости через устройство турбобур начинает работать, использу  определенный перепад давлени , завис щий от расхода жидкости, прокачиваемой через турбину 2.which requires expansion of the trunk. When pumping fluid through the device, the turbo-drill starts working using a certain pressure drop depending on the flow rate of the fluid pumped through the turbine 2.

Под действием иерепада давлени , возникающего в турбине, шток 7 с порщнем 6 перемещаетс  вниз внутри полого вала 3 турбобура . Нижн   часть щтока 8, взаимодейству  при этом с секци ми породоразрушающих органов 5, переводит их в рабочее положение.Under the action of pressure and pressure occurring in the turbine, the rod 7 with the force 6 moves downwards inside the hollow shaft 3 of the turbodrill. The lower part of the stem 8, while interacting with the sections of the rock cutting bodies 5, transfers them to the working position.

Таким образом, устройство, использу  перепад давлени , возникающий в турбобуре, позвол ет расшир ть ствол скважины без дополнительных затрат гидравлической мощности.Thus, the device, using the pressure drop occurring in the turbo-drill, allows the wellbore to be expanded without additional cost of hydraulic power.
