Abstract
Various embodiments of magneto-hydrodynamic connection pumps are discussed. In some cases, the pumps include: a body forming an inner channel, a first connection part on a first side of the tube, a second connection part on a second side of the tube; an anode electrode on an inside wall of the body, a cathode electrode located on the inside wall of the body at a location opposite the anode electrode, and one or more permanent magnets attached to or embedded into an outside wall of the body.
Claims18
A magneto-hydrodynamic (MHD) connection pump, comprising:
- a body forming an inner channel,
- wherein the body comprises a first groove and a second groove along an axis direction of the body, and
- wherein each of the first groove and the second groove has an opening in the axis direction of the body;
- a first connection part on a first side of the body;
- a second connection part on a second side of the body
- wherein the first connection part is attached to the first groove, and wherein the second connection part is formed by forming threads in the second groove;
- an anode electrode on an inside wall of the body;
- a cathode electrode located on the inside wall of the body at a location opposite the anode electrode;
- and
- one or more permanent magnets attached to or embedded into an outside wall of the body.
A downhole tubing connection system, the system comprising:
- a first magneto-hydrodynamic (MHD) connection pump located at a first location in a wellbore, wherein the first MHD connection pump comprising:
- a body forming an inner channel;
- a first connection part on a first side of the body;
- a second connection part on a downstream side of the body;
- an anode electrode on an inside wall of the body;
- a cathode electrode located on the inside wall of the body at a location opposite the anode electrode;
- and
- one or more permanent magnets attached to or embedded into an outside wall of the body;
- and
- a second MHD connection pump located at a second location in the wellbore, wherein the second MHD connection pump comprising:
- a body forming an inner channel;
- a first connection part on a first side of the body;
- a second connection part on a second side of the body;
- an anode electrode on an inside wall of the body;
- a cathode electrode located on the inside wall of the body at a location opposite the anode electrode;
- and
- one or more permanent magnets attached to or embedded into an outside wall of the body;
- a first type connection pump located at a third location in the wellbore, wherein the first type connection pump is different from the first MHD connection pump and the second MHD connection pump;
- a second type connection pump located at a fourth location in the wellbore, wherein the second type connection pump is different from the first MHD connection pump and the second MHD connection pump,
- wherein the third location is between the first location and the second location, and
- wherein the second location is between the third location and the fourth location.
