Abstract

FIELD: well drilling. SUBSTANCE: extension is made in the form of metal case and nozzle made of resistant to wear material. The nozzle length is more than twice as large as the largest diameter of passing hole. The nozzle consists of sections. Each section is attached to case internal surface through integral, gap-free, for example, glue connection. Nozzle sections may be made of different ceramic materials. Extension design allows one to shorten the distance between the area of mud ejection to the bottom and increase its mechanical effect on the rock being drilled out. The extension may be of rather high resistance to wear by using common technology of powder metallurgy. EFFECT: high resistance to wear. 3 cl, 2 dwg

Насадка выполнена в виде металлического корпуса и сопла, изготовленного из износостойкого материала. Сопло, длина которого более чем вдвое превышает величину наибольшего диаметра его проходного отверстия, состоит из секций, каждая из которых прикреплена к внутренней поверхности корпуса посредством неразъемного беззазорного, например клеевого, соединения. Секции сопла могут быть выполнены из разных керамических материалов. Конструкция насадки позволяет приблизить зону истечения струи бурового раствора к забою и повысить за счет этого ее механическое воздействие на разбуриваемую горную породу. Насадка может быть изготовлена с достижением высокой износостойкости с применением обычной технологии порошковой металлургии.The nozzle is made in the form of a metal casing and nozzle made of wear-resistant material. The nozzle, the length of which is more than twice the size of the largest diameter of its orifice, consists of sections, each of which is attached to the inner surface of the casing by means of a one-piece gapless, for example, glue connection. The nozzle sections can be made of different ceramic materials. The design of the nozzle allows you to bring the zone of flow of the mud stream to the bottom and thereby increase its mechanical effect on the rock being drilled. The nozzle can be made to achieve high wear resistance using conventional powder metallurgy technology.
