    • Disclosed herein is a system for enhancing the recovery of gas in a perforated interval of a gas well. The system features a tubing string having a dead string attached for reducing the flow area of the annulus in the perforated interval, thereby reducing the critical velocity of the gas, i.e., the velocity required to overcome backpressure due to fluids in the well column. The system includes a ported member for receiving gas from the annulus into the tubing string. The ported member and the dead string are isolated from each other by a retrievable plug. The disclosed system provides access from the surface through the dead string for diagnostic or corrective operations. The system also provides delivery of reagents such as foamers to the perforated region to further reduce the critical velocity.
    • 本文公开了一种用于增强气井的穿孔间隔中气体回收的系统。 该系统具有连接有死角的管柱,用于减少穿孔区间中的环空的流动面积,从而降低气体的临界速度,即克服由于井柱中的流体引起的背压所需的速度。 该系统包括用于将气体从环形空间接收到管柱中的端口构件。 移动的成员和死亡字符串通过可检索的插头彼此隔离。 所公开的系统提供从表面到死点的访问以用于诊断或纠正操作。 该系统还提供诸如起泡剂的试剂到穿孔区域的递送以进一步降低临界速度。

    • Integrated axially varying engine mufflers, and associated methods and systems are disclosed. An arrangement in accordance with one embodiment of the invention includes a tailcone having a tapering external surface, a cavity disposed within the surface, and an engine muffler disposed within the cavity. The engine muffler can have a tapering outer surface, a porous inner surface disposed inwardly from the outer surface, and a plurality of cells disposed between the outer surface and the inner surface in fluid communication with the perforations of the inner surface. The inner surface can be positioned adjacent to an exhaust gas flow path having an entrance aperture and an exit aperture. Cells positioned toward the entrance aperture can have a first dimension extending away from the gas path, and cells positioned toward the exit aperture can have a second, different, dimension extending away from the exhaust gas path. Accordingly, the tapered muffler can be integrated with the tapered tailcone, and can provide sounds attenuation over a range of frequencies.
    • 集成的轴向变化的发动机消声器以及相关的方法和系统被公开。 根据本发明的一个实施例的装置包括具有锥形外表面的尾管,设置在表面内的空腔和设置在腔内的发动机消声器。 发动机消声器可以具有锥形的外表面,从外表面向内设置的多孔内表面,以及设置在外表面和内表面之间的与内表面的穿孔流体连通的多个单元。 内表面可以邻近具有入口孔和出口孔的废气流动路径定位。 朝向入口孔定位的细胞可以具有远离气体路径延伸的第一尺寸,并且朝向出口孔定位的细胞可以具有远离废气路径延伸的第二不同的尺寸。 因此,锥形消音器可以与锥形尾音一体化,并且可以在一定频率范围内提供声音衰减。

    • A cone support for use with a stud, the cone support includes a hollow truncated cone with an apex and a base. The hollow truncated cone includes an apex aperture disposed at the apex and a base aperture disposed at the base. The apex aperture has a threaded internal diameter. The apex aperture and base aperture communicate with a cone chamber, the cone chamber is disposed within the interior of the cone and between the apex aperture and the base aperture. The stud is placeable within the apex aperture, the cone chamber and the base aperture such that the cone support protects the stud from shear forces when the stud is stressed perpendicular to its axis.
    • 锥形支撑件用于螺柱,锥形支撑件包括具有顶点和基部的中空截锥体。 中空截头圆锥​​体包括设置在顶点处的顶点孔口和设置在基部处的基部孔口。 顶点孔具有螺纹内径。 顶孔和底孔与锥室连通,锥室设置在锥体内部和顶孔与底孔之间。 螺柱可以放置在顶点孔,锥体腔和基座孔内,使得锥形支架在螺柱紧紧地垂直于其轴线时保护螺柱免受剪切力的影响。
