Изобретение относится к области бурения скважин, а именно - к устройствам для бурения скважин с одновременным спуском обсадных колонн. Устройство включает колонну труб, к башмаку которой присоединен расширитель. Корпус гидравлического вставного забойного двигателя в рабочем положении фиксируется внутри колонны труб. Пилотное долото присоединено к валу двигателя. Расширитель присоединен к колонне труб посредством упорно-радиального подшипника. Это обеспечивает передачу осевой нагрузки на расширитель от колонны труб, состоящей из обсадных труб.The invention relates to the field of drilling, namely, to devices for drilling wells with simultaneous descent of casing strings. The device includes a pipe string, to the shoe of which an expander is attached. The housing of the hydraulic plug-in downhole motor in the working position is fixed inside the pipe string. The pilot bit is attached to the engine shaft. The expander is connected to the pipe string by a thrust bearing. This ensures the transmission of axial load to the expander from the pipe string, consisting of casing pipes.
