Abstract
Многоступенчатый шарошечный буровой инструмент, бурголовка, расширитель, стабилизатор, долото, включающий многоступенчатые шарошки, отличающееся тем, что, с целью увеличения механической скорости бурения за счет усиления разрушения резанием в горизонтальном направлении и вводом в процесс бурения разрушение резанием в вертикальном направлении путем формирования боковой открытой ступенчатой поверхности со ступеньками оптимального размера, полностью разрушаемыми в процессе их формирования с минимальными энергетическими затратами, отдельный опережающий венец любой шарошки у бурголовок, расширителей, стабилизаторов удален от последующего другой шарошки по оси долота на 0,04-0,06 D с шириной ступеньки 0,02-0,04D где D - диаметр инструмента, а у долот те же соотношения сохраняются на внешнем конусе при максимально вписываемой ступенчатости на внутреннем конусе, причем значения соотношений зависят от глубины скважины, неглубокие скважины требуют меньших соотношений, глубокие - больших.Multistage roller cone drilling tool, burgole head, expander, stabilizer, chisel, including multistage roller cones, characterized in that, in order to increase the mechanical drilling speed by enhancing the fracture by cutting in the horizontal direction and introducing the fracture in the vertical direction into the drilling process by forming a side open stepped surface with steps of optimal size, completely destroyed during their formation with minimal energy costs, about the separate leading crown of any cone at the burgole traps, expanders, stabilizers is removed from the subsequent other cone along the axis of the bit by 0.04-0.06 D with a step width of 0.02-0.04D where D is the diameter of the tool, and the bits have the same ratios stored on the outer cone at the maximum entered step on the inner cone, and the ratio values depend on the depth of the well, shallow wells require lower ratios, deep - large.
