Abstract
Multi-functional fluid-driven power generation units, modular power generation units, and drilling systems with a power generation unit are presented herein. A power generation unit for powering one or more downhole tools in a drill string is disclosed. The power generation unit includes a housing that is configured to couple to a downhole portion of the drill string and receive at least a portion of fluid flowing through the drill string. The power generation unit also includes a fluid-driven motor assembly with a drive shaft configured to output rotational drive forces generated by the motor assembly. An electrical generator is operatively coupled to the drive shaft and configured to convert the rotational drive forces generated by the motor assembly into electrical power. In addition, a hydraulic pump is operatively coupled to the drive shaft and configured to convert the rotational drive forces generated by the motor assembly into hydraulic power.
