Abstract
A downhole drill pipe may comprise a transducer disposed therein, capable of converting energy from flowing fluid into electrical energy. A portion of a fluid flowing through the drill pipe may be diverted to the transducer. After passing the transducer, the diverted portion of the fluid may be discharged to an exterior of the drill pipe. To generate electrical energy while not obstructing the main fluid flow from passing through the drill pipe, the transducer may be disposed within a lateral sidewall of the drill pipe with an outlet for discharging fluid exposed on an exterior of the lateral sidewall.
Claims20
A downhole transducer assembly, comprising:
- a drill pipe capable of passing a fluid flow there through;
- and
- a course capable of diverting a portion of the fluid flow to a transducer capable of converting energy from the diverted portion into electrical energy, the transducer including a positive displacement motor attached to a generator, the positive displacement motor including a rotor and a stator, the stator including a nonelastic interior surface;
- wherein the rotor includes a helically shaped exterior, eccentrically rotatable within the stator, the stator having a helically shaped interior, wherein the helically shaped interior of the stator includes more lobes than the helically shaped exterior of the rotor.
A downhole transducer assembly, comprising:
- a drill pipe capable of passing a fluid flow there through;
- and
- a course capable of diverting a portion of the fluid flow to a transducer capable of converting energy from the diverted portion into electrical energy, the transducer including a turbine attached to a generator, wherein the turbine is adjustable relative to the diverted portion of fluid flow.
A downhole transducer assembly, comprising
- a drill pipe capable of passing a fluid flow there through;
- and
- a course capable of diverting a portion of the fluid flow to a transducer capable of converting energy from the diverted portion into electrical energy, the transducer including a turbine attached to a generator, wherein the turbine is interchangeable.
