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.
Claims21
A shaped charge, comprising:
- a carrier;
- an oxidizer component housed within the carrier;
- a fuel component housed within the carrier, wherein the oxidizer component and the fuel component are retained in a non-detonable state relative to one another;
- and
- a hinge coupled to an end of the carrier and supporting the carrier for pivotal movement, the carrier pivotal about the hinge between a first position and a second position, the carrier retaining the oxidizer component and the fuel component in the non-detonable state relative to one another while the carrier is in the first position, wherein the oxidizer component and the fuel component activate from the non-detonable state to a detonable state in response to an increase in temperature and the pivotal movement of the carrier about the hinge from the first position to the second position that mixes the oxidizer component and the fuel component within the carrier.

A shaped charge, comprising:
- a carrier;
- an oxidizer component housed within the carrier;
- a fuel component housed within the carrier;
- and
- a degradable barrier separating the oxidizer component and the fuel component to maintain, the oxidizer component and the fuel component in a non-detonable state relative to one another, wherein the oxidizer component and the fuel component activate from the non-detonable state to a detonable state in response to an increase in temperature, and wherein the increase in temperature induces mixing of the oxidizer component and the fuel component within the carrier.

- a carrier;
- an oxidizer component housed within the carrier;
- a fuel component housed within the carrier, wherein the oxidizer component and the fuel component are retained in a non-detonable state relative to one another;
- a degradable barrier separating the fuel component and the oxidizer component in the non-detonable state in the carrier;
- and
- a hinge coupled to an end of the carrier and supporting the carrier for pivotal movement, the carrier pivotal about the hinge between a first position and a second position, the carrier retaining the oxidizer component and the fuel component in the non-detonable state relative to one another while the carrier is in the first position, wherein the oxidizer component and the fuel component activate from the non-detonable state to a detonable state in response to an increase in temperature of the shaped charge and the pivotal movement of the carrier about the hinge from the first position to the second position that mixes the oxidizer component and the fuel component within the carrier.
