Abstract

A wireline coupler that connects a first data wireline to a second data wireline comprises: a first housing that is attached to the first data wireline, wherein the first housing comprises an electromagnet; a second housing that is attached to the second data wireline, wherein the second housing comprises a metal; wherein the electromagnet forms a magnetic field when electrical data flows in the first wireline, and wherein the magnetic field attracts the metal of the second housing and causes the first housing to connect with the second housing, such that first data wireline is operationally connected with the second data wireline.

Claims

1. A wireline coupler that connects a first data wireline to a second data wireline comprising:

a first housing that is attached to the first data wireline, wherein the first housing comprises an electromagnet, and the first data wireline is permanently or removably attached to a first pipe section of a tubing string;

a second housing that is attached to the second data wireline, wherein the second housing comprises a metal, and the second data wireline is permanently or removably attached to a second pipe section of the tubing string;

wherein the electromagnet forms a magnetic field when electrical data flows in the first wireline, and wherein the magnetic field attracts the metal of the second housing and causes the first housing to physically connect with the second housing, such that the first data wireline is operationally connected with the second data wireline.

2. The wireline coupler of claim 1, wherein the first and second data wirelines are operative to perform one of:

controlling a tool, relaying information about the tool, relaying information about an environment adjacent to the tool, relaying sensor information, relaying information or other data from various user applications, or combinations thereof.

3. The wireline coupler of claim 2, wherein the tool is one of a drill bit, a perforating gun, a core sampler, a sampling system, a slickline sampling system, a sensor, a packer, or combinations thereof.

4. The wireline coupler of claim 2, wherein the information is one of telemetry, revolutions per minute, temperature, orientation, depth, angle, flow rate, pressure, the concentration of particulate, other information, or combinations thereof.

5. The wireline coupler of claim 1, wherein the electromagnet comprises a metal and wherein the metal is selected from the group consisting of iron, nickel, cobalt, rare earth elements, and combinations thereof.

6. The wireline coupler of claim 1, wherein the metal is selected from the group consisting of iron, nickel, and combinations thereof.

7. The wireline coupler of claim 1, wherein the first wireline carries a data signal, wherein the data signal comprises a carrier wave and data, a radio frequency signal, power, or combinations thereof.

8. The wireline coupler of claim 1, further comprising:

at least one fitting that is located on the first housing or the second housing; and

a receiver that is located on the other of the second housing or the first housing, which is adapted to receive the fitting;

wherein the fitting and the receiver act to align the first data wireline and the second data wireline.

9. A well system comprising:

a first pipe section having a first wireline that is associated with the first pipe section, wherein the first wireline has a male housing located at one end of the first wireline and a female housing located at the other end of the first wireline, wherein the male housing comprises a first electromagnet and the female housing comprises a first metal; and

a second pipe section having a second wireline that is associated with the second pipe section, wherein the second wireline has a male housing located at one end of the second wireline and a female housing located at the other end of the second wireline, wherein the male housing comprises a second electromagnet and the female housing comprises a second metal;

wherein the male housing of the first wireline is placed proximate to the female housing of the second wireline,

whereby when the first wireline is energized, the male housing of the first wireline is attracted to the female housing of the second wireline to physically couple the male housing of the first wireline to the female housing of the second wireline, and the first wireline is operationally connected to the second wireline, and

whereby when the first wireline is de-energized, the male housing of the first wireline loses attraction to the female housing of the second wireline, and the first wireline is operationally disconnected to the second wireline.

10. The well system of claim 9, further comprising a controller that is operatively connected to the first wireline.

11. The well system of claim 9, further comprising a tool or sensor that is connected to the male housing of the second wireline.

12. The well system of claim 9, wherein at least the first and second wirelines are located inside of the first and second pipe sections.

13. The well system of claim 9, wherein at least the first and second wirelines are located outside of the first and second pipe sections.

14. The well system of claim 9, wherein at least the first and second wirelines are a data wireline.

15. The well system of claim 9, further comprising:

a third pipe section having a third wireline that is associated with the third pipe section, wherein the third wireline has a male housing located at one end of the third wireline and a female housing located at the other end of the third wireline, wherein the male housing comprises a third electromagnet and the female housing comprises a third metal;

wherein the male housing of the second wireline is placed proximate to the female housing of the third wireline,

whereby when the second wireline is energized, the male housing of the second wireline is attracted to the female housing of the third wireline to physically couple the male housing of the second wireline to the female housing of the third wireline, and the second wireline is operationally connected to the third wireline, and

whereby when the second wireline is de-energized, the male housing of the second wireline loses attraction to the female housing of the third wireline, and the second wireline is operationally disconnected from the third wireline.

16. A method of connecting a first pipe section to a second pipe section of a tubing string in a well system comprising:

providing a source of power to a first electromagnet, wherein the first electromagnet is part of a male housing of a first wireline, wherein the first wireline is associated with the first pipe section;

positioning the first wireline adjacent to a second wireline, wherein the second wireline is associated with the second pipe section, wherein the second wireline comprises a female housing, and wherein the female housing comprises a metal;

connecting the first pipe section to the second pipe section such that the male housing of the first wireline is located proximate to the female housing of the second wireline, wherein the step of providing the source of power forms a magnetic field such that the male housing attracts the female housing to the male housing; and

allowing the first wireline and the second wireline to create a physical and electrical connection with one another in response to the magnetic field.

17. A method of quickly disconnecting a first wireline from a second wireline in a well system comprising:

removing a source of power to a first electromagnet, wherein the first electromagnet is part of a male housing of the first wireline, wherein the first wireline is permanently or removably attached to a first pipe section of a tubing string, wherein the step of removing causes an existing magnetic field between the first electromagnet of the first wireline and a metal of a female housing to cease, wherein the female housing is part of the second wireline, and wherein the second wireline is permanently or removably attached to a second pipe section of the tubing string; and

allowing or causing the first wireline to become physically disconnected from the second wireline as a result of removing the source of power to the first electromagnet to cease the existing magnetic field between the first electromagnet of the first wireline and the metal of the female housing.

18. The method of claim 17, further comprising:

disconnecting the first pipe section from the second pipe section;

substituting a third pipe section for the first pipe section; and

connecting a third wireline of the third pipe section to the second wireline.
