摘要： An apparatus and method are disclosed for aligning equipment lowered from the ocean surface with a fixed subsea structure without the use of guidelines. The apparatus comprises a guide frame including primary and secondary members, a mating guide base including primary and secondary members, vertical channeling means and rotational engagement means. In the practice of the method, the frame is generally positioned above the base using known means of limited precision. Using remote means, the frame is first lowered to vertically channel the primary members into alignment, then rotated until the secondary members are engaged and finally lowered further to fully land the frame on the base.
摘要翻译： 公开了一种用于将从海洋表面降低的设备与固定海底结构对准的装置和方法，而不使用指南。 该装置包括一个引导框架，该引导框架包括一个和第二个构件，一个配合的引导基座，包括一个和第二个构件，垂直的引导装置和旋转接合装置。 在该方法的实践中，框架通常使用有限精度的已知方法定位在基底之上。 使用远程装置，首先将框架降低以使主构件垂直地通向对准，然后旋转直到次构件接合并最终进一步降低以将框架完全落在基座上。

摘要： Method and apparatus for altering the downhole flow path of control fluids or the like in oil and gas wells. A downhole side pocket mandrel in a tubing string has interconnected thereto a supply conduit from the surface and a plurality of receiving conduits. Each receiving conduit is connected to a control device. A plurality of different plug assemblies is provided, each for completing within the mandrel pocket when disposed therein a different hydraulic flow path between the supply conduit and one or more receiving conduits. The plug assemblies are insertable into and retrievable from the mandrel pocket by conventional running tools. Any desired control device may thereby be controlled at the surface with a single supply conduit by selection of the proper plug assembly. In a preferred embodiment, the plug assemblies are comprised of a plurality of subplugs which may be interconnected in differing orders to form the desired plug assembly.
摘要翻译： 用于改变油气井中控制流体等的井下流路的方法和装置。 管柱中的井下侧袋心轴与其相连，从表面和多个接收导管连接到供应管道。 每个接收导管连接到控制装置。 提供多个不同的插头组件，每个插头组件用于在设置在供给导管和一个或多个接收导管之间的不同液压流路的情况下在心轴袋内完成。 插头组件可以通过常规的运行工具插入并从芯棒袋中取回。 因此，任何期望的控制装置可以通过选择适当的插头组件而通过单个供应导管来控制在表面。 在优选实施例中，插头组件由多个子插头构成，其可以以不同的顺序互连以形成所需的插头组件。

摘要： A method and apparatus for remotely replacing damaged guideposts attached to a subsea structure are provided. A receptacle is permanently attached to the subsea structure. The guidepost is inserted into the receptacle and is releasably connected thereto by one or more radially-oriented, spring loaded lock pins. Damaged guideposts are removed by applying an upward vertical force to the guidepost sufficient to shear the lock pin or lock pins. The upward vertical force is applied by a replacement tool capable of being remotely operated from the surface of the body of water. Following removal of the damaged guidepost, a new guidepost is inserted into the receptacle. Lock pins mounted in the new guidepost retract into the guidepost as it is being inserted. When fully inserted, the lock pins extend and engage a retaining groove formed in the receptacle thereby firmly locking the new guidepost in place.
摘要翻译： 提供一种用于远程更换附接到海底结构的损坏路标的方法和装置。 容器永久地连接到海底结构。 导轨插入插座并通过一个或多个径向定向的弹簧加载的锁定销可释放地连接到插座。 通过向导轨施加向上的垂直力足以剪切锁定销或锁定销来去除损坏的导轨。 向上的垂直力由能够从水体表面远程操作的替换工具施加。 拆除损坏的路标后，将新的路标插入插座。 安装在新导轨上的锁定销在插入时缩回到导轨中。 当完全插入时，锁定销延伸并接合形成在容器中的保持槽，从而将新的导轨牢固地锁定在适当位置。
