Downhole power generation system and method
First Claim
1. A downhole power generation system, comprising:
- a tubular power generation device configured to be disposed in an annular space around a portion of a production tubing, wherein the power generation device is switchable between a power generation mode and a bypass mode;
a power storage device electrically coupled to the tubular power generation device and configured to store power generated by the power generation device;
wherein the power generation device comprises at least one power generation path and at least one bypass path, wherein the at least one power generation path comprises at least one power generation mechanism which generates power when traversed by fluid;
wherein the at least one power generation path is open in the power generation mode; and
wherein the at least one power generation path is closed in the bypass mode and the power generation mechanism is isolated from the at least one bypass path.

Abstract
A downhole power generation system includes a tubular power generation device configured to be disposed in an annular space around a portion of a production tubing, wherein the power generation device is switchable between a power generation mode and a bypass mode. The system also includes a power storage device electrically coupled to the tubular power generation device and configured to store power generated by the power generation device. The power generation device comprises at least one power generation path and at least one bypass path. The at least one power generation path comprises at least one power generation mechanism which generates power when traversed by fluid. The at least one power generation path is open in the power generation mode and closed in the bypass mode.

8. A downhole power generation system, comprising:
-
a tubular power generation device comprising a first end and a second end, an outer profile and an inner profile extending between the first end and the second end, the inner profile defining a central orifice configured to receive a length of production tubing therethrough, the power generation device comprising; at least one power generation path extending from the first end to the second end, the at least one power generation path comprising a fluid driven power generation mechanism disposed therein, wherein the power generation device further comprises; at least one bypass path extending from the first end to the second end, the at least one bypass path isolated from the at least one power generation path, wherein the tubular power generation device is switchable between a power generation mode and a bypass mode, the power generation path being open in the power generation mode and closed in the bypass mode. - View Dependent Claims (9, 10, 11, 12, 13, 14)
