Definitions
- the outside of the plug 310 that is visible through the holes 320-322 may be coated with the same material that makes up the waveguide body 300 or that is used to coat the inside surface of the waveguide body 300 or by some other conductive material. This enables the radiation to propagate through the waveguide 300 and not be affected by the holes.
- the material may be a metal.
- FIG. 4 is a cross-sectional diagram showing waveguide segments 400, 401 coupled by a breakable dielectric plug 420, according to various
- the cuts 501, 601, 701 may have a sealant lining the cut surface between the two pieces.
- a sealant may provide improved protection for the vacuum within the segment 500 so that foreign matter present on the cut surfaces does not provide microscopic pathways for the ambient pressure to enter the segment 500.
- the sealant might also act as a glue holding the pieces together as long as this glue is weak enough to not prevent the pieces from being separated by the internal pressure of oil flowing through the waveguide. Thus the glue breaks in response to the internal flow of oil within the waveguide or safety waveguide segment body.
- FIG. 8 is a cross-sectional diagram showing external lips 804, 805 on a waveguide or waveguide segment 800, according to various embodiments.
- the lips 804, 805 provide additional surface area for the ambient pressure to push against in order to provide a stronger force for holding two pieces of a segment together.
- the embodiment of inserting a plastic pipe (coated on its inner surface with a metal) into a strong metal pipe with bad inside surface properties may be useful as a dielectric lining even if the metal waveguide is a standard waveguide without any safety features.
- the flow of oil through the waveguide may not be preventable but the problems related to the smoothness and the electric and magnetic properties of the outside waveguide may be reduced or eliminated.
- the plastic pipe may be metal-coated on its outside so that the plastic acts as the dielectric lining.
- the above-described embodiments may be incorporated in one location of a waveguide or in multiple locations.
- a plurality of the safety waveguide segments may be incorporated into the waveguide.
- the waveguide may also incorporate a combination of the various embodiments of the safety waveguide segment.
- the drillstring 908 (perhaps including the drill pipe 918 and the BHA 920) may be rotated by the rotary table 910.
- the BHA 920 may also be rotated by a motor (e.g., a mud motor) that is located down hole.
- the drill collars 922 may be used to add weight to the drill bit 926.
- the drill collars 922 may also operate to stiffen the bottom hole assembly 920, allowing the bottom hole assembly 920 to transfer the added weight to the drill bit 926, and in turn, to assist the drill bit 926 in penetrating the surface 904 and subsurface formations 990.
- a workstation 992 including a controller 996 may include modules comprising hardware circuitry, a processor, and/or memory circuits that may store software program modules and objects, and/or firmware, and combinations thereof.
- the workstation 992 may also include modulators and demodulators for modulating and demodulating data transmitted downhole through the waveguide 900 or received through the waveguide 900 from the downhole environment.
- the workstation 992 and controller 996 are shown near the rig 902 only for purposes of illustration as these components may be located at remote locations.
- FIG. 10 is a flowchart of a method for constructing a waveguide, according to various embodiments.
- a waveguide may be constructed by coupling a plurality of waveguide segments together.
- One embodiment of a resulting waveguide is illustrated in FIG. 11 and described subsequently.
- the waveguide is configured to propagate a signal between a surface controller and a bottom hole assembly.
- At least one of the safety waveguide segments are coupled into the waveguide. At least one safety waveguide segments is configured to divert oil out of the waveguide.
- the safety waveguide segment may be coupled into the waveguide such that a dielectric plug that seals each waveguide segment is shared between adjacent waveguide segments, such as illustrated in FIG. 4.
- FIG. 11 is a cross-sectional diagram showing a waveguide constructed of a plurality of waveguide segments, according to various embodiments.
- This waveguide is made up of a plurality of waveguide segments 1100-1102, such as illustrated in FIG. 1.
- Example 7 the subject matter of Examples 1-6 can further include a vacuum or gas in the waveguide segment body, wherein the waveguide segment body is coupleable to a second waveguide segment, containing vacuum or gas, by the at least one dielectric plug, wherein the at least one dielectric plug is moveable or breakable by a pressure in the second waveguide segment.
- Example 10 the subject matter of Examples 1-9 can further include a plurality of lips coupled to the waveguide segment body, wherein each lip of the plurality of lips is coupled to an opposing side of a cut that separates the plurality of pieces such that a gap between the plurality of lips is open to a vacuum in the waveguide segment body.
