摘要： A bending shock de-coupler for use with a perforating string can include perforating string connectors at opposite ends of the de-coupler. A bending compliance of the de-coupler may substantially increase between the connectors. A well system can include a perforating string including at least one perforating gun and multiple bending shock de-couplers, each of the de-couplers having a bending compliance, and at least two of the bending compliances being different from each other. A perforating string can include a bending shock de-coupler interconnected longitudinally between two components of the perforating string. A bending compliance of the bending shock de-coupler may substantially decrease in response to angular displacement of one of the components a predetermined amount relative to the other component.

摘要： A shock de-coupler for use with a perforating string can include perforating string connectors at opposite ends of the de-coupler, a longitudinal axis extending between the connectors, and a biasing device which resists displacement of one connector relative to the other connector in both opposite directions along the longitudinal axis, whereby the first connector is biased toward a predetermined position relative to the second connector. A perforating string can include a shock de-coupler interconnected longitudinally between components of the perforating string, with the shock de-coupler variably resisting displacement of one component away from a predetermined position relative to the other component in each longitudinal direction, and in which a compliance of the shock de-coupler substantially decreases in response to displacement of the first component a predetermined distance away from the predetermined position relative to the second component.

摘要： A system and a method provide a downhole mechanical energy absorber that protects downhole tools from impact loads and shock loads that occur during run-in contacts, tool drops, perforating blasts, and other impact events. A continuous localized inelastic deformation of a tube is a primary energy absorber in a load limiting design of the downhole mechanical energy absorber.

摘要： A perforating apparatus (50) includes a carrier gun body (52) having a plurality of radially reduced sections (54). The radially reduced sections (54) have a nanocomposite outer layer (72). A charge holder (62) is positioned within the carrier gun body (52). A plurality of shaped charges (56) are supported by the charge holder (62). The shaped charges (56) each have an initiation end and a discharge end. The discharge ends of the shaped charges (56) are disposed proximate the radially reduced sections (54) of the carrier gun body (52) such that the jets formed upon detonation of the shaped charges (56) travel through the radially reduced sections (54). The nanocomposite outer layers (72) of the radially reduced sections (54) enable enhanced performance of the perforating apparatus (50) in high pressure and high temperature wellbores.
