FIELD: mining.
SUBSTANCE: modular tool to be used in underground formations is proposed. The tool includes the first module, the second module and one or more connection devices for connection of the first and the second modules. Particularly, the first module includes the first heavy-weight drill pipe that at least partially forms an external part of the tool. It includes the first engagement mechanism on its first end of the pipe and the second engagement mechanism on its second end. The first module also includes a through channel for passage of drilling mud. The second module has a similar configuration. Connection of at least one line of hydraulic system is performed by means of one or more connection devices. Line of hydraulic system hydraulically connected to external part of the tool and electric channel for transfer of electric power and/or data between modules.
EFFECT: improving operating reliability of the module.
