摘要： A pressure equalization apparatus can include separate longitudinal bores which form a continuous flowpath, the flowpath alternating direction between the bores, and the bores being interconnected at opposite ends thereof. A well system can include a well tool with a chamber therein containing an assembly in a dielectric fluid, and a pressure equalization apparatus including a flowpath having one end connected to the chamber, and the other end connected to a source of a another fluid, the flowpath extending in opposite directions between the flowpath ends through multiple separate bores. A method of installing a well tool can include attaching a mandrel to the well tool, then lowering the well tool at least partially into the well suspended from the mandrel, and then securing a pressure equalization apparatus to the mandrel, a flowpath of the apparatus being connected to a chamber of the well tool containing an assembly.

摘要： A safety valve for use in a subterranean well can include a housing assembly having a flow passage extending longitudinally through the housing assembly. An outer diameter of the housing assembly is eccentric relative to the flow passage. A well tool can include a magnetic coupling between magnet devices. One magnet device includes a series of magnets which are unequally spaced circumferentially about the other magnet device. Another safety valve can include a longitudinally extending flow passage, a closure device which selectively permits and prevents flow through the flow passage, and an outer diameter which is eccentric relative to the flow passage.
摘要翻译：用于地下井中的安全阀可以包括具有沿纵向延伸穿过壳体组件的流动通道的壳体组件。壳体组件的外径相对于流动通道偏心。井具可以包括磁体装置之间的磁性耦合。一个磁体装置包括围绕另一个磁体装置周向不等距地间隔开的一系列磁体。另一安全阀可包括纵向延伸的流动通道，选择性地允许和防止流动通过流动通道的闭合装置以及相对于流动通道偏心的外径。

摘要： A magnetically coupled safety valve with satellite outer magnets. A safety valve includes a housing having multiple chambers extending longitudinally in a pressure bearing wall of the housing, and multiple magnetic devices, each of the magnetic devices being reciprocably disposed in a corresponding one of the chambers. Another safety valve includes multiple first magnetic devices, a second magnetic device magnetically coupled to the first magnetic devices, with the first magnetic devices being circumferentially spaced apart and encircling the second magnetic device. Yet another safety valve includes a housing having a pressure bearing wall, and multiple magnetic devices, each of the magnetic devices being reciprocably disposed in the housing wall, and each of the magnetic devices being completely surrounded by the housing wall.
