Abstract

Способ регулирования направления бурения скважины в подземной формации, при этом способ включает обеспечение трубчатой бурильной колонной; обеспечение буровым долотом, закрепляемым на нижнем конце бурильной колонны, причем буровое долото содержит механические режущие средства, которые формируют лезвие коронки, а также содержит несколько сопл для выпуска бурового флюида, при этом указанные сопла находятся в разном азимутальном положении относительно лезвия колонки, между входным каналом бурового долота и указанными соплами имеется полость; вращение бурового долота при подаче из бурильной колонны бурового флюида с твердыми частицами и испускании указанного флюида через указанные сопла с целью углубления буровой скважины; и изменение концентрации твердых частиц в жидкой фазе бурового флюида, испускаемого через указанные сопла вращающего бурового долота, чтобы концентрация твердых частиц в жидкой фазе бурового флюида, проходящего через каждое из сопл, относительно увеличивалась, когда соответствующее сопло находится в выбранном первом угловом секторе забоя ствола скважины, по сравнению со вторым угловым сектором.A method for regulating a direction of drilling a well in a subterranean formation, the method comprising providing a tubular drill string; providing a drill bit fixed at the lower end of the drill string, and the drill bit contains mechanical cutting means that form the crown blade, and also contains several nozzles for discharging drilling fluid, while these nozzles are in different azimuthal positions relative to the column blade, between the inlet channel a drill bit and said nozzles have a cavity; rotating the drill bit while feeding from the drill string a drilling fluid with solid particles and emitting said fluid through said nozzles to deepen the borehole; and changing the concentration of solid particles in the liquid phase of the drilling fluid emitted through said nozzles of the rotating drill bit so that the concentration of solid particles in the liquid phase of the drilling fluid passing through each of the nozzles is relatively increased when the corresponding nozzle is in the selected first corner sector of the wellbore , compared to the second corner sector.
