摘要： A technique to install a tool in a well includes running the tool into the well and fixing the tool to the well with a fixing agent without pumping the fixing agent through a central passageway of the tool. The tool may be a perforating gun that includes a casing body that includes a longitudinal axis. The perforating gun may also include a fin and a perforating charge. The fin radially extends from the casing body, and the perforating charge is attached to the fin and is oriented to generate a perforation jet in a radial direction away from the longitudinal axis of the casing body.

摘要： A method of dampening stress waves propagated from the detonation of an explosive device in a wellbore to protect a device positioned downhole including the steps of positioning a shock dissipater between an explosive device and a package; detonating the explosive device propagating a stress wave toward the shock dissipater and the package; and reflecting a portion of the stress wave in the shock dissipater. The shock dissipater may have one or more interface formed between materials of dissimilar acoustic impedances. The shock dissipater may reflect a compressive portion of the stress wave at one interface and a tensile portion of the stress wave at another interface.

摘要： Safety apparatus is disclosed for providing ballistic train interruption in a perforating system. The safety apparatus comprises a generally tubular shaped housing having first and second ends which are fabricated to permit the housing to be positioned at any location in the perforating system. The apparatus comprises first and second ballistic sections in the housing and a third ballistic section which is rotatably mounted in the housing to move between a disarmed position and an armed position based on downhole pressure. Upon retrieval of the perforating system from the wellbore, the safety apparatus functions to return a third ballistic section to its disarmed position. Additionally, apparatus is provided to permanently disable the third ballistic section to insure that no inadvertent detonation of the guns occurs when retrieving the system from a wellbore.
