Abstract
1. Способ сооружения скважины, включающий бурение ее породоразрушающим инструментом забойного снаряда, соединенного с двойной бурильной колонной, с непрерывным удалением шлама от забоя скважины, транспортировку шлама потоком отработанного рабочего тела под давлением по центральному каналу двойной бурильной колонны, отличающийсятем, что для бурения скважины используют двойную бурильную колонну, образованную невращающейся наружной трубой и размещенной в ней буровой штангой, передающей крутящий момент и осевое усилие на забойный снаряд с породоразрушающим инструментом, причем одновременно с бурением скважины осуществляют затяжку в нее указанной наружной трубы, которую после завершения бурения оставляют в скважине в качестве обсадной трубы, при этом центральным каналом двойной бурильной колонны является канал буровой штанги.2. Способ по п.1, отличающийся тем, что в двойной бурильной колонне используют наружную трубу из неметаллического материала.1. The method of constructing a well, including drilling its rock cutting tool downhole connected to a double drill string, with the continuous removal of sludge from the bottom of the well, transporting the slurry by the flow of the spent working fluid under pressure through the Central channel of the double drill string, characterized in that they use for drilling a well a double drill string formed by a non-rotating outer pipe and a drill rod placed in it, transmitting torque and axial force to the bottom hole d with a rock cutting tool, and at the same time as the well is being drilled, the specified outer pipe is drawn into it, which, after the completion of drilling, is left as a casing in the well, while the central channel of the double drill string is the drill rod channel. 2. The method according to claim 1, characterized in that in the double drill string an outer pipe of non-metallic material is used.
