Description

Изобретение относитс  к о-бласти бурени  скважин, в частности к бурильным инструментам .The invention relates to the field of well drilling, in particular to drilling tools.

Известны наддолотные отражатели, -Б-КЛЮчающие волновод, выполненный в виде трубы , жестко соединенной с долотом, и экран, представл ющий собой трубу большого поперечного сечений.Naddolotnye reflectors are known, -B-LOOTING waveguide, made in the form of a pipe rigidly connected to the bit, and a screen, which is a pipe of a large cross-section.

С целью повышени  эффективности отражател  в работе, стенки волновода вьшолнены переменной толщины.In order to increase the efficiency of the reflector in operation, the walls of the waveguide are made of variable thickness.

На чертеже показан отражатель в продольном разрезе.The drawing shows a reflector in longitudinal section.

Он включает волновод / переменной толщины , жестко соединенный с корпусом долота 2, и экран 3.It includes a waveguide / variable thickness, rigidly connected to the body of the bit 2, and the screen 3.

Наддолотный отражатель работает следующим образом.Nadolotny reflector works as follows.

При прокатывании зубьев долота по заоою в волноводе распростран ютс  ударные импульсы сжати . Часть энергии ударных имлульсов рассеиваетс  в бурильной колонне , а часть, отразившись от экрана, возвращаетс  к долоту.When the bit teeth are rolled along the bottom in the waveguide, shock compression pulses are propagated. Some of the energy of the shock impulses is dissipated in the drill string, and some, reflected from the screen, returns to the bit.

Вследствие равенства длины волновода и полуволны продольных колебаний, энерги  отраженных импульсов реализуетс  при разрушении породы.Due to the equality of the length of the waveguide and the half-wave of longitudinal oscillations, the energy of the reflected pulses is realized when the rock is destroyed.
