Dope relief method for wedge thread connections
View Patent ↗A method for making-up a wedge thread connection comprising a pin member and a box member includes applying a pipe dope to at least one of the pin member and the box member, wherein the pin member and the box member comprise corresponding wedge threads, reducing the viscosity of the pipe dope at least temporarily, and rotating the pin member relative to the box member to make-up the wedge thread connection, wherein the rotation occurs while the viscosity of the pipe dope is at least temporarily reduced. A collar to be used with a tong assembly in making-up a threaded connection between a pin member and a box member includes at least one power unit configured to temporarily reduce the viscosity of pipe dope applied to at least one of the pin member and the box member, and an inner surface having a selected diameter to correspond to an outer diameter of at least one of the pin member and the box member.
1. A method to make-up a wedge thread connection, the method comprising:
applying a pipe dope to at least one of a pin member and a box member;
reducing the viscosity of the pipe dope at least temporarily;
rotating the pin member relative to the box member to make-up the wedge thread connection; and
wherein the rotation occurs while the viscosity of the pipe dope is at least temporarily reduced.
2. The method of claim 1 , wherein the temporarily reduced viscosity of the pipe dope is achieved by heating the wedge thread connection to a selected temperature.
3. The method of claim 2 , wherein the selected temperature is at least a downhole service temperature for the wedge thread connection.
4. The method of claim 1 , wherein the temporarily reduced viscosity of the pipe dope is achieved by heating the pipe dope to a selected temperature.
5. The method of claim 1 , wherein the temporarily reduced viscosity of the pipe dope is achieved by vibrating the wedge thread connection.
6. The method of claim 1 , further comprising:
attaching a make-up collar around at least one of the pin member and the box member, wherein the make-up collar comprises at least one of a heat source and a vibration source.
7. The method of claim 6 , wherein the make-up collar comprises a hinged portion.
8. The method of claim 6 , wherein the make-up collar comprises an inner surface having a selected diameter to correspond to an outer diameter of the box member.
9. A method to make-up a wedge thread connection comprising a pin member and a box member, the method comprising:
applying a pipe dope to at least one of the pin member and the box member, wherein the pin member and the box member comprise corresponding wedge threads;
temporarily reducing the viscosity of the pipe dope; and
making-up the wedge thread connection while the viscosity of the pipe dope is temporarily reduced.
10. The method of claim 9 , wherein the temporarily reduced viscosity of the pipe dope is achieved by heating the wedge thread connection to a selected temperature.
11. The method of claim 10 , wherein the selected temperature is at least a downhole service temperature for the wedge thread connection.
12. The method of claim 9 , wherein the temporarily reduced viscosity of the pipe dope is achieved by pre-heating the pipe dope to a selected temperature.
13. The method of claim 12 , wherein the selected temperature is at least a downhole service temperature for the wedge thread connection.
14. The method of claim 9 , wherein the temporarily reduced viscosity of the pipe dope is achieved by vibrating the wedge thread connection.
15. The method of claim 9 , wherein the making-up of the wedge thread connection comprises rotating the pin member relative to the box member.
16. The method of claim 9 , wherein the making-up of the wedge thread connection comprises rotating the box member relative to the pin member.
