Abstract
Abstract A protective clamp assembly is provided for securing a conductor lines to the production tubing of oil and gas wells and providing for efficient transition of the conductor lines past the various connections of the well tubing. To prevent crushing or other damage to those portions of the conductor lines that are located at tubing connections, the clamp assembly of this invention provides for efficient transition of the conductor lines past the enlarged connections of the tubing. Under circumstances where the tubing is brought into forcible contact with the well casing within which it is received, the protective clamp assembly contacts the well casing thus preventing the well casing from applying crushing force to the conductor lines.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
205 words
An assembly for establishing protective transition of conductor line about the spaced enlargements formed by threaded connections on a tubular member in a well comprising: first and second generally semicylindrical body sections; hinge means along each side of each of said body sections for receiving a hinge pin to secure the assembly on the tubular member; cooperating means on said body sections and the tubular member to interlock the assembly on the tubular member; stiffener portions extending radially outwardly of each of said body sections on each side of said hinge means to protect said hinge means against damage; enclosure means, said enclosure means comprising an internal recess formed on at least one of said body sections by a longitudinal inwardly open channel which extends radially outward of the body section for receiving the conductor line therein to protect the conductor line against crushing as it transitions the spaced enlargements formed by the tubular member threaded connections; and said channel having openings at each end for receiving the conductor line and said channel further including an inwardly curved portion adjacent at least one end thereof to direct the conductor line to close proximity with the tubular member adjacent at least one end of said channel.
Claim 2
Dependent Claim
205 words
An assembly for establishing protective transition of conductor line about the spaced enlargements formed by threaded connections on a tubular member in a well comprising: first and second generally semicylindrical body sections; hinge means along each side of each of said body sections for receiving a hinge pin to secure the assembly on the tubular member; cooperating means on said body sections and the tubular member to interlock the assembly on the tubular member; stiffener portions extending radially outwardly of each of said body sections on each side of said hinge means to protect said hinge means against damage; enclosure means, said enclosure means comprising an internal recess formed on at least one of said body sections by a longitudinal inwardly open channel which extends radially outward of the body section for receiving the conductor line therein to protect the conductor line against crushing as it transitions the spaced enlargements formed by the tubular member threaded connections; and said channel having openings at each end for receiving the conductor line and said channel further including an inwardly curved portion adjacent at least one end thereof to direct the conductor line to close proximity with the tubular member adjacent at least one end of said channel.
Claim 3
Dependent Claim
47 words
The assembly of claim 1 wherein said cooperating means include inwardly projecting flanges formed at least on one end of said body sections, and a groove in the tubular member for receiving the inwardly projecting flanges therein to interlock the assembly about the tubular member threaded connections.
Claim 4
Dependent Claim
43 words
The assembly of claim 1 wherein said cooperating means includes inwardly extending flanges formed at each end of said body sections and projecting shoulders on the threaded connection for engagement with said flanges to interlock the assembly about the tubular member threaded connections.
Claim 5
Dependent Claim
53 words
The assembly of claim 1 wherein said channel is of greater longitudinal extent than the length of said body sections to define extremities, and wherein said inwardly curved portion is on each of said extremities to direct the conductor line to close proximity with the tubular member adjacent each end of said channel.
Claim 6
Dependent Claim
28 words
The assembly of claim 1 wherein said stiffener portions extend radially outwardly of each of said body sections at least to the same extent as said hinge means.
Claim 7
Dependent Claim
36 words
The assembly of claim 5 wherein said stiffener portions are of a width greater than the width of said hinge means, and wherein said stiffener portions are of a longitudinal extent greater than said hinge means.
Claim 8
Dependent Claim
23 words
The assembly of claim 6 wherein said stiffener portions are tapered at each end to assist in guiding the assembly into the well.
