Abstract
A gas-operated, fixed-volume, downhole setting tool includes a mandrel having an upper portion and a lower portion. The mandrel has a first end on the upper portion and a second end on the lower portion. The mandrel also includes an interior combustion chamber having a first end proximate to the first end of the mandrel and having an interior upper portion. The setting tool further includes a pressure bulkhead with a pressure igniter disposed in the mandrel at the first end of the mandrel in the interior upper portion of the mandrel. The pressure igniter is sealed to at least a first threshold pressure. The pressure bulkhead and pressure igniter form a seal on the first end of the mandrel and thereby define a fixed volume for combustion gases. Other settings tools and assemblies are presented.
Claims19
A gas-operated, fixed-volume, downhole setting tool comprising:
- a mandrel having an upper portion and a lower portion;
- a barrel piston having a first end and a second end, and wherein the barrel piston extends over at least a portion of the mandrel when in an in-line configuration and releasably coupled in a relative position to the mandrel when in the in-line configuration;
- wherein the mandrel has a first end on the upper portion and a second end on the lower portion;
- wherein the mandrel includes an interior combustion chamber having a first end proximate to the first end of the mandrel and having an interior upper portion;
- a pressure bulkhead disposed in the mandrel at the first end of the mandrel in the interior upper portion of the mandrel;
- a pressure igniter coupled in the pressure bulkhead having an ignition control end and an ignition distribution end;
- wherein the pressure igniter is sealed to at least a first threshold pressure;
- wherein the pressure bulkhead and pressure igniter form a seal on the first end of the mandrel and thereby define a fixed volume for combustion gases;
- and
- wherein the pressure igniter is not directly coupled to any component that is in contact with the mandrel other than the pressure bulkhead.
A gas-operated, fixed-volume, downhole setting tool comprising:
- a mandrel having an upper portion and a lower portion;
- a barrel piston having a first end and a second end, and wherein the barrel piston extends over at least a portion of the mandrel when in an in-line configuration and releasably coupled in a relative position to the mandrel when in the in-line configuration;
- wherein the mandrel has a first end on the upper portion and a second end on the lower portion;
- wherein the mandrel includes an interior combustion chamber having a first end proximate to the first end of the mandrel and having an interior upper portion;
- a pressure bulkhead disposed in the mandrel at the first end of the mandrel in the interior upper portion of the mandrel;
- a pressure igniter coupled in the pressure bulkhead having an ignition control end and an ignition distribution end;
- wherein the pressure igniter is sealed to at least a first threshold pressure;
- wherein the pressure bulkhead and pressure igniter form a seal on the first end of the mandrel and thereby define a fixed volume for combustion gases;
- and
- wherein the pressure igniter ignition distribution end is supported in place by only the coupling between the pressure igniter and the pressure bulkhead.
A gas-operated, fixed-volume, downhole setting tool comprising:
- a mandrel having an upper portion and a lower portion;
- a barrel piston having a first end and a second end, and wherein the barrel piston extends over at least a portion of the mandrel when in an in-line configuration and releasably coupled in a relative position to the mandrel when in the in-line configuration;
