Oilfield Equipment Manufacturing and Repair
Zhigermunayservis LLP (ZMS) manufactures drilling bits.
The drilling tool is manufactured in 4 and 5-point turning and milling workshops.
The ZMS drill bit technologies enable the Customers to drill faster, longer and more efficiently in order to minimise the costs per drilled meter. The high technology innovations are based on the in-depth research, expert opinions of multi-functional groups, simulation and own laboratory studies.
The following bits have been manufactured to date:
- dimensions from 123 mm to 444 mm
- three, four, five and six vanes
- for drilling of soft, medium soft and medium rocks.
This is not the limit! A team of engineers are constantly working on improvement of the tools. The bits are manufactured based on the individual assignment depending on the drilling conditions.
Bit optimisation cycle includes the following steps:
Manufacturing of the PDC bits with steel body includes:
- Load equalization
- Tungsten carbide coating to improve wear resistance
- High quality synthetic diamond cutters
Examples of Our Successes
