Е 21 В 4/04, опубл. 15.04.1989).  A device for drilling wells is known, which contains an electromechanical drill suspended on a load-carrying cable and equipped with an annular crown, a core-receiving pipe, an electric motor with a gearbox, a winch on which a load-carrying cable, a mast with a roller and a source of electrical energy are wound (see copyright certificate SU jYe 1472613, class E 21 B 4/04, publ. 04/15/1989).

Буровой инструмент 3 снабжен ультразвуковыми излучателями 20. Устройство для бурения скважины работает следующим образом. Вначале другой буровой установкой бурится скважина глубиной достаточной для полного углубления в скважину устройства для бурения скважины. После этого устройство для бурения скважины устанавливают в подготовленную скважину. Посредством гидронасоса и/или компрессора с использованием блоков гидроуправления, управляемых непосредственно оператором или с использованием, например компьютера, на котором установлено соответствующее специально для этого разработанное программное обеспечение, путем подачи по шлангу 8 высокого давления газообразной или жидкой рабочей среды в гидроцилиндры 13 раздвигают распорные плашки 14 и таким образом плотно останавливают в скважине корпус 2.

After the housing 2 has been fixed in the well, the drilling tool 3 is started by feeding through a high-pressure hose 7 of a gaseous or liquid working medium into a hydraulic motor 5, which drives the hollow shafts 1 1 and 12 and the drilling tool 3 from it in rotation in the opposite directions by means of the drive hollow shaft 7. After the start of rotation, the drilling tool 3 is axially fed using a mechanical drive 16 for axial movement of the guide pipe 15 while supplying compressed air or drilling fluid through the channels 18 and 19 into the bottom of the well to blow around the upper part of the drilling tool 3 and to prevent the image Bani deposits in the bottom of the well. The drilling tool 3 is equipped with ultrasonic emitters 20, which intensify the process of destruction of the drilled rock. After drilling a well with a drilling tool for the length of the hollow shafts 11 and 12, the drilling tool 3 is stopped, resting on the bottom (bottom) of the drilled well and the spacers 14 are removed from the stop in the wall of the drilled well by relieving pressure in the hydraulic cylinders 13. Then lower the body 2 of the device for drilling a well under its own weight and using a mechanical drive 16 until the hollow shafts 11 and 12 of the drilling tool 3 enter the housing 2. Then, the spacers 14 are extended to their it is time to wall 6 wells. The housing 2 is again fixed in the drilled well, after which the above-described operation of drilling a new section of the well is repeated.
