摘要: A fiber optic delivery system and side pocket mandrel removal system. In one example, a system for making optical connections in a well includes an optical connector positioned in the well, and another optical connector displaceable into operative connection with the first optical connector after the first optical connector is positioned in the well. In another example, a method of making optical connections in a well includes the steps of: positioning a tubular string in the well; then installing an assembly in the tubular string, the assembly including an optical connector; and then displacing the optical connector into operative engagement with another optical connector in the tubular string.

摘要: The present invention is an apparatus for relieving annular fluid pressure between nested casing strings. The invention includes a pressure relief collar formed of a cylindrical housing and a set of end connections disposed on opposite sides of the cylindrical housing. The end connections join adjacent sections of casing string of the same diameter. A plurality of equally spaced centralizer blades are secured to the outer surface of the cylindrical housing. Each centralizer blade is equipped with a pressure relief mechanism, which opens the passage of fluid from an outer annulus between adjacent casing strings to an inner annulus between different adjacent casing strings and also prevents backflow of fluid. One or more inlet and outlet filters may also be employed to remove solids and other contaminants from the fluid entering the pressure relief mechanism. The invention also has application as a pressure relief collar for eccentric casing strings.
摘要翻译: 本发明是一种用于缓解嵌套套管柱之间的环形流体压力的装置。 本发明包括由圆柱形壳体形成的减压环和设置在圆柱形壳体的相对侧上的一组端部连接。 端部连接连接相同直径的套管柱的相邻部分。 多个等间距的扶正器叶片固定到圆柱形壳体的外表面。 每个扶正器叶片配备有一个压力释放机构,该压力释放机构使流体从相邻的套管柱之间的外部环空通过到不同相邻的套管柱之间的内部环形空间,并且还防止流体回流。 还可以使用一个或多个入口和出口过滤器来从进入压力释放机构的流体中除去固体和其它污染物。 本发明还可用作偏心套管柱的压力环。
