Abstract
A non-detonable shaped charge capable of becoming detonable upon activation. The shaped charge may be utilized for use with a perforating gun in oilfield applications. In this regard, during transport and other handling in advance of reaching the application site, the charge may be non-detonable. However, upon an intentionally directed activation, such as through heating, the shaped charge may be detonable.
Claims22
-17. (canceled)
A shaped charge, comprising:
- an oxidizer component;
- and
- a fuel component, wherein the oxidizer component and the fuel component are in a non-detonable state relative to one another;
- and
- wherein the shaped charge is configured to activate from the non-detonable state to a detonable state in response to an increase in temperature of the shaped charge and a movement of the shaped charge that mixes the oxidizer component and the fuel component within the shaped charge.
The shaped charge of claim 7, comprising a degradable barrier separating the fuel component and the oxidizer component in the non-detonable state.
A shaped charge, comprising:
- an oxidizer component;
- and
- a fuel component, wherein the oxidizer component and the fuel component are in a non-detonable state relative to one another;
- and
- wherein the shaped charge is configured to activate from the non-detonable state to a detonable state in response to an increase in temperature of the shaped charge, wherein the increase in temperature induces mixing of the oxidizer component and the fuel component within the shaped charge.
A shaped charge, comprising:
- an oxidizer component;
- a fuel component, wherein the oxidizer component and the fuel component are in a non-detonable state relative to one another;
- and
- a degradable barrier separating the fuel component and the oxidizer component in the non-detonable state;
- and
- wherein the shaped charge is configured to activate from the non-detonable state to a detonable state in response to an increase in temperature of the shaped charge and a movement of the shaped charge that mixes the oxidizer component and the fuel component within the shaped charge.
