摘要： A method and apparatus for manufacturing any given length of a completion filter assembly is described. An outer perforated jacket is assembled over the filter media, which is itself placed over a coarse support screen or drainage layer. In the preferred embodiment, the drainage layer and outer jacket have end rings such that when advanced through a die are pushed together with the filter media in between to effect a seal of the subassembly. The subassembly can then be placed on a support pipe which is perforated, and if metallic, the end rings are welded to the support pipe to complete the assembly. Optionally, many of the components can be made of materials which lend buoyancy to the assembly so that when it is advanced into a long lateral, it will float to assist in its proper positioning.

摘要： A composite landing collar is disclosed which is preferably adhesive bonded to the liner string using a high temperature epoxy. The spacing during bonding is maintained within dimensional limits using spacers. The body features a bi-directional material, with an appropriate ratio in the warp and fills directions, for about a quarter of the wall thickness. A unidirectional material with the fibers axially aligned aids in reduction of thermal stresses in the thick wall during curing, as well as reducing shear stress concentration along the adhesive bonding interface.
摘要翻译：公开了一种复合着陆衣领，其优选地使用高温环氧树脂粘合到衬垫绳上。使用间隔件将接合期间的间隔保持在尺寸限度内。身体具有双向材料，在经向和填充方向上具有适当的比例约四分之一的壁厚。具有纤维轴向排列的单向材料有助于在固化期间减小厚壁中的热应力，以及降低沿粘合界面的剪切应力集中。
