摘要： A perforating gun includes a charge tube having shaped charges affixed thereto. Each shaped charge includes a radially outward pointing post adapted to receive a detonator cord. A retention member installed on the post provides a compressive force that energetically couples the detonator cord to the post. The radially outermost portion of the retention member is radially flush with or radially recessed relative to the radially outermost portion of each post. In one embodiment, the retention member has a rounded medial portion, a central opening and a pair of locking tabs that point radially inward to the central opening. Each post may include a slot for receiving the detonator cord and a circumferential groove that is adapted to receive the locking tabs.

摘要： A perforating gun train for perforating two or more zones of interest includes two or more gun sets made up of guns, detonators, and other associated equipment. In one embodiment, the gun sets are connected with connectors that can convey activation signals between the gun sets. The firing of a gun set creates this conveyed activation signal either directly or indirectly. In one arrangement, a surface signal initiates the firing of a first gun set while subsequent firings are initiated by firing of the gun sets making up the gun train. An exemplary connector is at least temporarily filled with signal conveyance medium adapted to transmit activation signals between the gun sets. In one embodiment, the signal conveyance medium is a liquid. The liquid can be added to the connector either at the surface or while in the wellbore.

摘要： A carrier tube for use in a wellbore perforating gun has inner and outer layers selected from materials of different, comparative physical properties. The inner layer has a higher compressive strength, and the outer layer has a higher yield strength. The inner layer enables the tube to withstand wellbore compressive pressures, which may, depending upon the material selected, include relatively high pressures, while the outer layer contains any fragments of the inner layer that result upon detonation of the gun. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要： An apparatus for providing zonal isolation in a wellbore includes a plurality of interlocking sealing elements having anchor elements at the opposing ends. Each anchor element sealingly engages a wellbore tubular whereas the interlocking sealing elements do not engage any portion of wellbore therebetween. In one exemplary application utilizes a wellhead and lubricator positioned over a wellbore under pressure and a conveyance device for conveying equipment into the wellhead. The first anchor, the second anchor and the plurality of interlocking sealing elements are separately conveyed into the wellbore with the conveyance device and sequentially assembled in the wellbore to provide zonal isolation.

摘要： A constant velocity universal joint is assembled as a crown ball meshed within a housing socket for rotation about respective rotational axes. The outside diameter of the crown ball is greater than the inside diameter of the socket. A plurality of channels, equally spaced around the crown ball perimeter are cut into the crown ball surface generally along or parallel with the crown ball drive axis. An arcuate cup is cut into each crown ball channel to confine a respective torque transfer element. A number, corresponding to the number of crown ball channels, of partial cylinder channels are cut into the inside surface of the housing socket. One of opposite side walls for each housing channel is given an arcuate radius corresponding to that of the force transfer elements. Ridges between adjacent crown ball channels mesh with ridges between adjacent housing socket channels. Torque transfer elements confined within said crown ball cups engage the partial cylinder wall of the housing channels to transfer drive forces between the crown ball and socket housing through a departure angle between the respective rotational axes.
