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.
Claims17
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 an exterior of the first end of the upper portion of the mandrel is configured to receive and mate with a firing head.
A bottom hole assembly comprising:
- a fracturing gun for perforating a well, wherein the fracturing gun includes an upper end and a lower end;
- a setting tool having an upper end and a lower end;
- wherein the setting tool comprises:
- 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 is disposed proximate 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 of the mandrel and a second end on the lower portion of the mandrel,
- wherein the mandrel includes an interior combustion chamber having a first end and a second end, and further having an upper interior portion,
- a pressure bulkhead disposed in the upper interior portion of the mandrel, and
- 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;
- a rig-up adapter having an upper end and a lower end, the rig-up adapter sized and configured at the lower end of the rig-up adapter to at least partially surround the upper end of the setting tool and is coupled by threads to the setting tool;
- and
- wherein the upper end of the rig-up adapter is sized and configured to extend into and mate with the lower end of the fracturing gun or another adapter and couple thereto.
A 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 is disposed proximate to 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 of the mandrel and a second end on the lower portion of the mandrel;
- wherein the mandrel includes an interior combustion chamber having an upper end and a lower end, and further comprising an upper interior portion;
- a pressure bulkhead disposed in the upper interior portion of the mandrel;
- a pressure igniter coupled in the pressure bulkhead, wherein the pressure igniter comprises 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;
- wherein the upper portion of the mandrel is sized and configured to mate and couple with an uphole component;
- wherein the upper portion of the mandrel is sized and configured to mate and couple with the uphole component using a threaded connection;
- and
- wherein the threaded connection comprises threads on an exterior surface of the mandrel.
