    摘要: A trigger including a carrier, a shuttle movably disposed on the carrier, an energy member disposed between the carrier and the shuttle, a degrade-on-demand trip member disposed to maintain potential energy in the energy member until activated. A method for operating a downhole tool including sending a signal to the trip member of the trigger, degrading the trip member, converting potential energy stored in the energy member from potential energy to kinetic energy, and actuating the downhole tool with the shuttle. A wellbore system including a borehole in a subsurface formation, a string in the borehole, a trigger disposed within or as a part of the string.

    摘要: The present invention discloses a method for assigning the carrier frequency in a trunking system, which includes: after the base station subsystem receiving a group call request, it assigns a carrier frequency reference for this group call, by which to establish the forward channels of the group users managed by the base station subsystem. With the method offered by the present invention, all the group members under a base station subsystem could be established on the same carrier frequency reference as far as possible, thereby sharing of the wireless channels.

    摘要: A downhole assembly includes a disintegrable article, which contains a polymer matrix comprising a polymer having an oxygen content of about 2 wt % to about 30 wt %; an energetic material configured to generate heat upon activation to facilitate a chemical decomposition of the polymer; and at least one of a reinforcing fiber or a filler. The disintegrable article is disintegrated by disposing the downhole assembly in a downhole environment; performing a downhole operation; exposing the polymer in the polymer matrix to the generated heat to chemically decompose the polymer producing a decomposed product containing a small molecule in a supercritical state; and disintegrating the disintegrable article with the small molecule in the supercritical state.
