摘要： A perforating gun may include a gun carrier extending in an axial direction and a tandem seal adapter (TSA). The gun carrier having a maximum outer carrier diameter. The TSA may include a first TSA region having a first TSA outer diameter, a second TSA region having a second TSA outer diameter, and a shoulder surface formed between an outer surface of the first TSA region and an outer surface of the second TSA region. The second TSA outer diameter may be larger than the first TSA outer diameter and smaller than the maximum outer carrier diameter. A portion of the gun carrier may abut with the shoulder surface.

摘要： A tandem seal adapter (TSA) for use with a wellbore tool may include a TSA body including a first end and a second end opposite the first end in an axial direction, a bore extending through the TSA body from the first end to the second end, an electrical contact assembly provided within the bore, the electrical contact assembly being configured to provide electrical connectivity through the bore. The electrical contact assembly may include a bulkhead provided within the bore. An axial position of a maximum outer diameter of the TSA body may overlap with the bulkhead in the axial direction. A portion of the bore overlapping in the axial direction with an entirety of the TSA body having an outer diameter equal to the maximum outer diameter may have a constant bore diameter.

摘要： A perforation gun assembly may include a single shaped charge holder, the shaped charge holder having a charge receiving structure and at least one projection extending from the charge receiving structure. A detonation cord and a detonator may be connected to the shaped charge holder. A top connector may be configured for connecting to a first base of the shaped charge holder and a bottom connector may be configured for connecting to a second based of the shaped charge holder. The perforation gun assembly may be positioned within an outer gun carrier of a perforation gun, and a tandem seal adapter may be positioned at least in part within the outer gun carrier.

摘要： A perforating gun system may include a first gun carrier and a second gun carrier connected to the first gun carrier. A perforating gun assembly may be provided in each gun carrier, the perforating gun assembly including a top connector, a plurality of charge holders, and at least one bottom connector. Upon rotation of the top connector, the one or more charge holders of the first gun carrier may be aligned in a zero-degree phasing with the plurality of charge holders in the second gun carrier, and the position of the top connector may be locked along the length of the second gun carrier.

摘要： A perforating gun assembly may include a first housing extending along a longitudinal axis and a tandem seal adapter (TSA). The first housing may include a coupling provided at a first end of the first housing. The TSA may include a TSA body and a seal element provided on an outer surface of the TSA body. At least part of the TSA may be positioned inside the first housing such that the seal element and the coupling intersect with a common plane that is perpendicular to the longitudinal axis.
