摘要： A downhole tool for use in a well bore comprises an onboard navigation system for determining the location of the tool within the well bore, wherein the tool is moved along at least a partial length of the well bore via an external force. A method of locating a downhole tool in a well bore comprises deploying the tool along at least a partial length of the well bore via an external force, and self-determining the location of the tool without receiving communications from the surface. In an embodiment, the tool is a well bore zonal isolation device.

摘要： A method of servicing a well bore comprises deploying into the well bore a zonal isolation device operable to self-set at a sensed location, and self-setting the zonal isolation device to hold at the sensed location without receiving command communications from the surface, wherein the zonal isolation device is deployed along at least a partial length of the well bore via an external force. Another method of servicing comprises deploying into the well bore a tool operable to self-activate at one or more locations, and self-navigating the tool to determine the one or more locations without receiving communications from the surface, wherein the tool is moved along at least a partial length of the well bore via an external force.

摘要： A perforating apparatus for a gun string is presented. The apparatus experiences an axial load and potentially a radial load during use. A central charge-carrier supports shaped-charges and substantially bears the axial load on the apparatus during use. The charge-carrier is positioned within an exterior sleeve and the plurality of shaped-charges, upon detonation, perforate the exterior sleeve. The exterior sleeve does not bear a substantial portion of the axial load on the apparatus and can therefore be thinner and cheaper than in prior art assemblies. An annular space can be defined between the charge-carrier and exterior sleeve. The exterior tubular can bear the radial load due to differential pressure in one embodiment. Alternately, the apparatus includes radial support members extending between the charge-carrier and sleeve for transmitting radial load to the charge-carrier. Alternately, the sleeve and charge-carrier abut one another along a substantial portion of the length of the charge-carrier.

摘要： A perforating apparatus (100) used to perforate a subterranean well. The perforating apparatus (100) includes a generally tubular gun carrier (106) and a charge holder (104) rotatably mounted within the gun carrier (106). At least one shaped charge (102) is mounted in the charge holder (104) and is operable to perforate the well upon detonation. A dynamically adjustable weight system (124) is operably associated to the charge holder (104). The dynamically adjustable weight system (124) is operable to adjust the center of gravity (120) of the charge holder (104) such that gravity will cause the charge holder (104) to rotate within the gun carrier (106) to position the at least one shaped charge (102) in a desired circumferential direction relative to the well prior to perforating.

摘要： A perforation gun string includes a perforation gun that forms at least part of the perforation gun string and a swellable material coupled to the perforation gun string. The swellable material is configured to be exposed to a downhole wellbore environment and to swell in response to exposure to the downhole wellbore environment. Further, the swellable material is configured to protrude beyond an outer surface of the perforation gun string when the swellable material swells.
