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
