Having an autonomous source is perhaps the most optimal and profitable way to solve the water supply problem. Moreover, it is extremely necessary if the process of hydrodrilling a well is used during construction. Using this technological process, well development will be quick and inexpensive, especially if you involve the MBU 125 drilling rig in the work.
Drilling rig MBU-125
The MBU 125 drilling rig is used when carrying out workover work, drilling exploration and production wells with downhole motors and a rotor, and in existing wells for kicking off the second table. This installation is capable of drilling a well to a depth of 2.7 kilometers.
A special feature of the MBU 125 mobile unit is that it can be used in temperate climates with a temperature range from -45° to +45°, in areas of those deposits where the hydrogen sulfide content is less than six percent.
The presented mobile drilling rig is produced in several cities of Russia, including Kostroma, Kungur and Petropavlovsk. The average price of a factory-installed installation that has passed factory tests and is fully ready for operation is about forty million rubles.

The installation consists of the following main blocks: – a lifting unit on a BAZ-69096 all-wheel drive chassis with increased load capacity – a mobile unit of a drilling base and receiving walkways on a three-axle trailer OZTP-84703
MBU-125 rigs are quite well-known all over the world, well-proven in operation in any conditions, mobile drilling complexes. The simplicity of their installation and operation puts them at the forefront in the segment of mobile drilling equipment, first of all, not forgetting the most important price-quality ratio.
For a long time, the main problem of the MBU-125 complexes was the need to modify the drilling complex on site, in light of problems that arose and the inconsistency of some components with drilling conditions. Our company managed to solve this problem. At the moment, we are ready to provide a complex that has been clearly tested over the years, modernized taking into account all the errors and inaccuracies in the standard installation.
Thanks to a number of engineering solutions, our company has managed to significantly increase the reliability of drilling equipment, which has a striking impact on the subsequent cost of service.
And finally, the most important thing: Our company offers not only installation, but a full range of services, starting with the manufacture of the installation and its infrastructure, ending with all issues related to its subsequent operation.
