摘要： A downhole tool, a nozzle assembly for the downhole tool and a nozzle. The nozzle assembly includes an orifice in a housing of the downhole tool. The orifice has a housing groove. A nozzle is insertable into the orifice, the nozzle including a nozzle groove. A release member secures the nozzle to the housing by disposing a first portion of the release member in the housing groove and a second portion of the release member in the nozzle groove. The first portion is removable from the second portion upon applying a force to the nozzle above a release threshold. The nozzle includes a body having an outlet end, a nozzle groove on a surface of the body for receiving a release member to secure the nozzle within a housing, and a seal groove for isolating the nozzle groove from an environment at the outlet end.

摘要： A downhole assembly includes a downhole tool including a degradable-on-demand material including: a matrix material; and, a unit in contact with the matrix material. The unit includes a core including an energetic material configured to generate energy upon activation to facilitate degradation of the downhole tool; and, an activator disposed in contact with the core, the activator including a triggering system having an electrical circuit and an igniter within the electrical circuit, the electrical circuit having an open condition and a closed condition, the electrical circuit configured to be in the closed condition after movement of an object downhole that engages directly or indirectly with the triggering system, and the igniter arranged to ignite the energetic material in the closed condition of the electrical circuit. In the open condition of the electrical circuit the igniter is inactive, and in the closed condition of the electrical circuit the igniter is activated.
