    • A method and apparatus are described for creating a fluid seal in a subterranean well structure having a fluid seal defect. The method comprises introducing a meltable repair material proximate a structure in a subterranean well which has a fluid seal defect or enhanced seal capacity is required or it is desired to temporarily or permanently hydraulically isolate a portion the well or strengthen the structural integrity of well tubulars or tubular hangers. Exothermic reactant materials are located proximate the meltable repair material. The exothermic reactant material is ignited or an exothermic reaction otherwise initiated which supplies heat to and melts the meltable repair material into a molten mass. The molten mass flows and solidifies across the structure and the fluid seal defect to effect a fluid seal in the subterranean well structure or the structural integrity is enhanced. Examples of preferred exothermic reactant materials include thermite, thermate, fusible chemical reactants such as ammonium chloride and sodium nitrate, and oxidizers and accompanying hydrocarbon based fuels. Examples of preferred meltable repair materials include solder or brazing materials and eutectic metals which expand upon cooling and solidifying from a molten state.
    • 描述了一种用于在具有流体密封缺陷的地下井结构中产生流体密封的方法和装置。 该方法包括在地下井中的结构附近引入可熔化的修复材料,其具有流体密封缺陷或需要增强的密封能力,或者期望临时或永久性地水力分离井的一部分或加强井管的结构完整性,或者 管状衣架。 放热反应物料位于可熔修补材料附近。 放热的反应物料被点燃或另外启动的放热反应,其向可熔化的修补材料供应热量并将其熔化成熔融物质。 熔融质量流过并固化在结构和流体密封缺陷上,以实现地下井结构中的流体密封,或增强了结构完整性。 优选的放热反应物材料的实例包括:铝,热,易熔化学反应物如氯化铵和硝酸钠,以及氧化剂和伴随的烃类燃料。 优选的可熔融修复材料的实例包括焊料或钎焊材料和在熔融状态下冷却和固化时膨胀的共晶金属。

    • Various embodiments described and illustrated herein provide one or more of systems, methods, software, and firmware to handle attack generated demand proactively using distributed virtualization. One goal of some such embodiments is to provide a time window of stable operational response within which an intrusion detection system may detect an attack and/or cause a countermeasure against the attacks to be activated. Demand excursions which are not caused by an attack are supported during the variability of demand providing transparent response to legitimate users of the system. These embodiments, and others, are described in greater detail below.
    • 本文描述和示出的各种实施例提供主动使用分布式虚拟化来处理攻击生成的需求的一个或多个系统,方法,软件和固件。 一些这样的实施例的一个目标是提供稳定的操作响应的时间窗口,入侵检测系统可以在其中检测攻击和/或引起针对要激活的攻击的对策。 在需求的变化中,对系统的合法用户提供透明的响应,支持不是攻击引起的需求偏移。 这些实施例和其他实施例在下面更详细地描述。
