    摘要: The embodiments described herein generally relate to a fluid pressure pulse generating apparatus with a primary seal assembly, back up seal assembly and pressure compensation device. The pressure compensation device comprises a membrane support and a longitudinally extending membrane system. The membrane support has a longitudinally extending bore therethrough for receiving a driveshaft of the fluid pressure pulse generating apparatus. The longitudinally extending membrane system comprising a longitudinally extending outer membrane sleeve and a longitudinally extending inner membrane sleeve with the inner membrane sleeve positioned inside the outer membrane sleeve. The membrane system is sealed to the membrane support to allow flexing of the membrane system in response to fluid pressure on either an inner longitudinal surface of the membrane system or an outer longitudinal surface of the membrane system and to prevent fluid on the inner longitudinal surface mixing with fluid on the outer longitudinal surface.

    摘要: Apparatus for attenuating a shock in a tool string, such as from an explosive, includes a body (28) which is inextensible, the body having means (34,36) for connecting it serially in a tool string, and an intermediate section (38) for undergoing plastic deformation to dissipate the shock energy. In a particular embodiment, the plastic deformation and serial energy dissipation occur in a hollow unitary body (28) having a cylindrical wall in which are defined a plurality of longitudinally spaced circumferential grooves (42).

    摘要: A compensator 1 for supporting an explosive severing device 2 in a bore hole 3 below a well head (not shown) and for damping forces arising on explosion of the explosive severing device 2 in the bore hole. The compensator 1 comprises two parts 4 (Figs. 1 to 4) and 5 (Figs. 5 and 6) mounted for relative longitudinal slidable motion. One part 4 has means 6 for supporting the explosive device 2 in the bore hole 3, and at least one of the parts (in this case both parts 4 and 5) has means in the form of through holes 7 for dissipating laterally, upwardly directed forces arising on explosion of the device in the bore hole.

    摘要: A technique facilitates mitigation of shock loads. Subterranean communication systems may comprise components susceptible to various shock loads. A shock mitigation system (30) is physically coupled with the subterranean communication system (28) to mitigate such shock loads. The shock mitigation system (30) comprises components selected to enable reduction of various effects of shock loads, e.g. shock loads resulting from perforating procedures, which could otherwise be detrimental to continued operation of the subterranean communication system.
