Wellbore power generating system for downhole operation
First Claim
1. A system for generating power from fluid flow in a wellbore comprising:
- a rotation member having magnetic properties and having a passageway through which objects may pass into the wellbore; and
a support mechanism coupling the rotation member inside the wellbore;
wherein fluid flow through the passageway of the rotation member causes the rotation member to rotate thereby generating a magnetic field that produces usable power.

Abstract
A power generating system (100) for a downhole operation (10) having production tubing (40) in a wellbore (12) includes a magnetized rotation member (110) coupled to the wellbore (12) within the production tubing (40), the rotation member (110) having a passageway (112) through which objects, such as tools, may be passed within the production tubing (40). Support braces (170, 172) couple the rotation member (110) to the production tubing (40) and allow the rotation member (110) to rotate within the production tubing (40). Magnetic pickups (150, 152) are predisposed about the rotation member (110) within the wellbore (12) and a power conditioner (200) is provided to receive currents from the magnetic pickups (150, 152) for storage and future use. The rotation member (110) rotates due to the flow of fluid, such as crude oil, through the production tubing (40) which causes the rotation member (110) to rotate and induce a magnetic field on the magnetic pickups (150, 152) such that electrical energy is transmitted to the power conditioner (200), the power conditioner able to store, rectify, and deliver power to any one of several electronic components within the wellbore (12).

21. A power generating system for a oil producing operation having production tubing in a downhole wellbore, the system comprising:
-
a magnetized rotation member coupled to the wellbore within the production tubing, the rotation member having a passageway through which objects may be passed within the production tubing;
a support mechanism coupling the rotation member to the production tubing and allowing the rotation of the rotation member within the production tubing;
magnetic pickups predisposed about the rotation member within the wellbore;
a motor for starting and stopping the rotation of the rotation member;
a control wire extending from outside the wellbore to the motor for allowing human operation of the motor from a point outside the wellbore;
a power conditioning unit; and
leads extending from the magnetic pickups to the power conditioning unit;
wherein the flow of fluid through the production tubing causes the rotation member to rotate and induce a magnetic field on the magnetic pickups such that electrical energy is produced and delivered to the power conditioning unit, the power conditioning unit capable of delivering usable power to any one of several electronic components within the wellbore. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A system for extracting fluids from a plurality of production zones intersected by a wellbore, the system including downhole power generation and comprising:
-
production tubing extending along a substantial length of the wellbore, the production tubing including at least one valve at each of the plurality of production zones with passages extending from the production zones to each valve permitting the flow of fluid from the plurality production zones into the production tubing via the valve; and
at least one magnetized rotation member coupled within the production tubing and predisposed to make contact with fluid flowing through the production tubing as a valve opens to permit fluid to flow from a production zone, the rotation member having a passageway through which objects may pass into the wellbore via the production tubing, wherein fluid flow through the passageway causes the rotation member to rotate thereby generating a magnetic field that produces useable power. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)
