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.

TBS1-178.NGT.M1 and TBS1-178.NGT.M2

Description

Turbodrills TBS1-178.NGT.M1 and TBS1-178.NGT.M2 are new universal turbodrill-whipstocks with an ultra-short arm to the point of axes curvature.

The turbodrill is available for drilling with impregnated and PDC bits in 212,7- 220,7 mm dia.

Turbodrill contains turbine section and bearing section as whipstock with angle adjuster. Angle adjuster is available with the following bend angles : 0°00', 0°13', 0°25', 0°37', 0°49', 1°00', 1°11', 1°20', 1°29', 1°37', 1°44', 1°50', 1°54', 2°00'. Flexible shaft of titanium alloy is used for torque transmission.

Highly efficient turbines of M1 and M2 types are used in turbine section of turbodrills. Both turbines are made of stainless steel by precision casting method. The turbine efficiency constitutes 68-70% at max. power.

The turbodrill bearing sections have axial sliding bearing, the operating surfaces made of synthetic diamond. This allows obtaining high power characteristics and increased overhaul life.
