The Conference “Import Substitution”

The company took part in the 3rd conference “Import Substitution” organized by PJSC “Variyoganneftegaz”. The report of our representative at one of the conference sections “Drilling and completion of wells” was extremely interesting for the representatives of PJSC “Variyoganneftegaz” and OJSC “Slavneft’ – Megionneftegaz”. We achieved mutual understanding with the general customers on the next steps in the introduction of innovative products developed by our specialists.

T2-127.NGT.M2

Description

Turbodrill T2-127.NGT.M2 has high speed of rotation and is used for drilling of wells with combination and impregnated bits of small diameter.

The turbodrill contains two turbine sections and bearing section. The turbine sections incorporate the turbine of high speed of rotation and low pressure drop. The turbine efficiency constitutes 68-70% at max. power. The turbodrill bearing section operates in mud and has axial sliding bearing, the operating surfaces made of synthetic diamond. This allows reaching high power characteristics and overhaul operation life (not less than 300 hours).
