    摘要： An apparatus includes a propellant chamber, an expansion chamber, an exit chamber comprising a port providing fluid communication outside the apparatus, and a longitudinal acceleration chamber. The longitudinal acceleration chamber includes a first end in fluid communication with the propellant chamber, a second end in fluid communication with the expansion chamber, and a longitudinal axis between the first end and the second end. An acceleration mass is slidably contained in the acceleration chamber. The acceleration chamber includes a propellant side between the propellant chamber and the acceleration mass, and a target side between the acceleration mass and the expansion chamber. A transfer piston is slidably positioned between the expansion chamber and the exit chamber. The transfer piston includes a first end projecting into the expansion chamber and aligned with the longitudinal axis of the acceleration chamber, and a second end projecting into the exit chamber.

    摘要： A retrievable float valve hanger tool assembly provides a hanger sub having a first upper connection for attaching the hanger sub, for example, threadably, to a drill string or work string. A second lower connection means on the sub provides both external and internal threaded (for example) connections, which allow the sub to be connected on its inner threads to a float valve canister and at its external threads to an extension which forms a protective housing about the float valve and its valve canister during operation. The device places the float valve below the joint of the sub and the extension so that an explosive charge can be detonated at the joint allowing easy removal of the float valve from the drill string in the event that the drill pipe becomes stuck. A continuous bore through the assembly allows fluid circulation through the tool in the work string and also allows the explosive charge to be lowered by wireline, for example, to the tool assembly at the appropriate joint. The explosive charge, detonated above the float valve aids in breaking the connection between the hanger sub and extension so that the float valve canister can be removed when the hanger sub and extension are disconnected.

    摘要翻译： 一种可检索的浮阀悬挂器工具组件提供了一种具有第一上部连接件的衣架子，用于将衣架子例如螺纹连接到钻柱或工作柱上。 子上的第二下连接装置提供外部和内部螺纹（例如）连接，其允许副在其内螺纹上连接到浮阀阀，并且在其外螺纹处连接到延伸部，形成保护壳体 浮球阀及其阀芯在运行过程中。 该装置将浮阀放置在副和延伸部的接头下方，使得在接头处可以引爆爆炸物，在钻杆被卡住的情况下容易从钻柱上移除浮阀。 通过组件的连续孔允许流体在工作串中循环通过工具，并且还允许通过电缆将爆炸装料降低到例如适当接头处的工具组件。 在浮阀上方引爆的爆炸物有助于破坏悬挂子和延伸部之间的连接，从而当悬挂子和延伸部分断开时，可以拆下浮阀罐。

    摘要： A “back-off” tool comprises a magazine cylinder having one distal end of a long mast rod secured to the lower end-face of a magazine cylinder. The magazine cylinder is attached to an electrically detonated firing head. A first plurality of blind hole cavities penetrate the magazine cylinder end-face around the mast rod junction. A second plurality of elongated detonation cord ends are inserted into high temperature grease filled magazine cylinder cavities. From the cavities, the detonation cord lengths are bound to the rod surface along the rod length by non-metallic cord. The tool assembly is secured to the end of a wireline or tubing string for downhole placement and detonation.

    摘要： Apparatus is disclosed for connecting the firing head of a downhole tool to a set of jars to allow the jars to jar up and jar down. The apparatus includes a firing head housing, a hammer located in the housing, and a spring urging the hammer toward a firing pin. A mandrel extends into the housing. It has one end connected to a jar and the other end connected to the hammer by a shear pin. The mandrel also has longitudinally spaced oppositely facing shoulders and one or more lock segments around the mandrel between the shoulders. The movement of the lock segments along the axis of the housing is limited and the lock segments engage the oppositely facing shoulders to limit axial movement of the mandrel relative to the housing in either direction when the pin is sheared and the hammer released to strike the firing pin.
