Description

Известны долота дл  бурени  нефт п 21Х скпажкн с зубь ми на шарошках , расположенными по пр мой кольцевой канавке. Така  конструкци  зуба шарошек не дает правильного скалывани  породы, ведет к быстрому износу зубьев и не обеспечивает равномерной работы.Chisels are known for drilling oil p 21X with knives on roller cones located in a straight ring groove. Such a design of the tooth of the cutters does not give the correct spallation of the rock, leads to rapid wear of the teeth and does not ensure uniform operation.

С целью усгранени  указанных недостатков, предлагаемое долото дл  бурени  скважин выполнено с зигзагообразными зубцами на шарошках (зигзагообразной кольцевой канавкой).In order to exacerbate these drawbacks, the proposed drill bit for drilling is made with zigzag teeth on the cones (zigzag ring groove).

На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.

Зигзагообразна  канавка 1 у шаронжи 2 может быть профрезерована нальцевой фрезой. Можно также иолучнть шарошку с такой конструкцией зуба путем отливки ее прецизиоииым способом.The zigzag groove 1 of a sharonzhi 2 can be milled by a face milling cutter. It is also possible to shape a roller with such a tooth structure by casting it in a precision way.

Конструкци  долота с зигзагообразным зубом примеиена как дл  бескорпусиых, так и дл  корпусных долот. Оиа обеснечнвает более нолное нокрытие забо  при разрушении его шарошкой, увеличивает прочность зубьев и может дать больший эффект при бурении скважии.Chisel construction with a zigzag tooth is suitable for both bodyless and solid chisels. Oia will make a more complete hole in the bottom when it is destroyed by a roller cutter, it increases the strength of the teeth and can give a greater effect when drilling a well.

Предмет изобретени Subject invention

Долото дл  буреии  скважин, отличаюшеес  тем, что зубцы его шарошек выполнены зигзагообразными.Chisel for borei wells, characterized in that the teeth of its cones are zigzag-shaped.
