摘要： An assembly employing multiple eccentric devices about a mandrel. The assembly is configured such that at least one of the eccentric devices is adjustably orientable relative another. Thus, for example, where the devices are packers disposed about completions tubing, the adjustable orientation may be utilized to ensure enough clearance is available for downhole advancement of the assembly. As such, the assembly may remain eccentric in nature without concern over damage during positioning, particularly to a communication line running to actuatable implements of equipment coupled to the completions assembly.
摘要翻译：围绕心轴采用多个偏心装置的组件。组件被构造成使得偏心装置中的至少一个相对于另一偏心装置可调节地定向。因此，例如，当设备是围绕完井管道设置的包装机时，可调节的定位可以用于确保足够的间隙可用于组件的井下提前。因此，组件本质上可以保持偏心，而不考虑定位期间的损坏，特别是涉及连接到完成组件的设备的致动器具的通信线路。

摘要： A completions system utilizing a unique hydraulic coupling. The system includes an upper completion stinger configured for coupling to a lower completion tubular. Both the stinger and the tubular are outfitted with hydraulic lines therethrough. Thus, as the stinger is coupled to the tubular, hydraulic lines are also coupled. However, the termination of each line is sealingly covered by a slidable sleeve in advance of attaining the coupling between the stinger and tubular. Therefore, the lines are protected from contamination during potentially significant periods of well deployment that may occur in advance of completed coupling and system installation. Furthermore, the manner of hydraulic coupling between the stinger and tubular reduces the likelihood of damage to the hydraulic lines during the installation process.
摘要翻译：使用独特的液压联轴器的完井系统。该系统包括配置成与下部完成管连接的上部完井托架。托管架和管状管都装有液压管路。因此，当托管架连接到管状时，液压管路也联接。然而，在获得托管架和管状物之间的联接的情况下，每条线的端接件被可滑动套管密封地覆盖。因此，在完成的联接和系统安装之前，可以在潜在的重要的井部署期间保护管线免受污染。此外，托管架和管道之间的液压耦合的方式降低了在安装过程中损坏液压管线的可能性。
