Abstract: A technique facilitates on-demand release of desired sections of a well string, e.g. sections of a perforating gun string, via at least one on-demand release tool. The on-demand release tool has an activation mechanism which may be selectively actuated to transition the on-demand release tool from a first loadbearing configuration to a second loadbearing configuration. The on-demand release tool may then be transitioned to a release stage which allows a first section of the on-demand release tool to be separated from a second section of the on-demand release tool by activating a release mechanism. In at least some applications, the on-demand release tool also comprises a ballistic transfer device to enable reliable ballistic transfer between sections of the perforating gun string.

Abstract translation: 一种技术有助于按需释放井串的期望部分，例如， 通过至少一个按需释放工具，穿孔枪串的部分。 按需释放工具具有激活机构，其可以被选择性地致动以将按需释放工具从第一承载构型转换到第二承载构型。 按需释放工具然后可以转换到释放阶段，其允许按需释放工具的第一部分通过激活释放机构与按需释放工具的第二部分分离。 在至少一些应用中，按需释放工具还包括一个弹道传送装置，以使射孔枪串的各部分之间能够进行可靠的弹道传递。
