Abstract
A propellant container for a perforating gun includes a lower cap, one or more pieces of propellant positioned within the lower cap, wherein at least one of the one or more pieces of propellant defines one or more through-holes, and an upper cap matable with the lower cap to secure the one or more pieces of propellant within the lower cap. A filler material is present within interstitial spaces between the one or more pieces of propellant.
Claims14
A propellant container for a perforating gun, comprising:
- a lower cap having an open end;
- two or more pieces of propellant housed within the lower cap;
- and
- an upper cap matable with the lower cap at the open end via an interference fit, an adhesive, a wax, a threaded interface, or a combination thereof,
- wherein mating the lower cap and the upper cap secures the two or more pieces of propellant within the propellant container for use within the perforating gun,
- wherein a rate of combustion of at least one of the two or more pieces of propellant increases at a greater than linear rate and a surface area of the at least one of the two or more pieces of propellant increases during combustion until consumed by the combustion, and
- wherein at least one of the two or more pieces of propellant does not combust at an increasing rate after being ignited.
4 more elements
A perforating gun, comprising:
- a charge tube;
- one or more shaped charges supported in the charge tube;
- one or more containers supported in the charge tube, wherein each container comprises:
- a lower cap having an open end;
- two or more pieces of propellant housed within the lower cap;
- and
- an upper cap matable with the lower cap at the open end via an interference fit, an adhesive, a wax, a threaded interface, or a combination thereof;
- and
- a detonating cord extending to each shaped charge and each container to ignite the one or more shaped charges and the two or more pieces of propellant in each container,
- wherein a rate of combustion of at least one of the two or more pieces of propellant increases at a greater than linear rate and a surface area of the at least one of the two or more pieces of propellant increases during combustion until consumed by the combustion,
- wherein at least one of the two or more pieces of propellant does not combust at an increasing rate after being ignited, and
- wherein mating the lower cap and the upper cap secures the two or more pieces of propellant within the propellant container for use within the perforating gun.
