摘要： A system and method for deployment of an isolation seal assembly wherein an isolation seal assembly is releasably attached to a reverse circulation debris removal tool. The system includes a debris removal tool having a head with an elongated snorkel extending from the head; and an isolation seal assembly attached to the head with a shear device so that the snorkel protrudes past the end of the isolation seal assembly. The isolation seal assembly further includes a tubular with a latch adjacent a first end, an external seal below the latch, and openings formed along tubular between latch and the seal. The debris removal tool is used to engage the isolation seal assembly with a lower completion assembly. The openings in the isolation seal assembly permit the debris removal tool to continue to function after the isolation seal assembly is engaged with the lower completion assembly.

摘要： Certain aspects are directed to a device designed to relieve compression in a length of pipe. The device provides a load ring that can absorb and isolate load until a shear sleeve is shifted and shear pins are sheared. A specific aspect provides a packer release compaction joint that has a shifting sleeve having a first internal shoulder configured to engage a shifting tool; a shear sleeve having a raised abutment; a load ring mounted on the shear sleeve, the load ring having an outer diameter and positioned forward of the first side of the raised abutment; a snap ring mounted around the outer diameter of the load ring. Action of a shifting tool against the first internal shoulder of the shifting sleeve causes the snap ring to move away from the load ring and move to the second side of the raised abutment.
摘要翻译：某些方面涉及一种设计用于减轻一段管道中压缩的装置。该装置提供负载环，其可以吸收和分离负载，直到剪切套筒移动并且剪切销被剪切。特定方面提供了一种封隔器释放压实接头，其具有一个移位套筒，该套筒具有构造成接合换档工具的第一内部肩部; 具有凸起基台的剪切套筒; 安装在所述剪切套筒上的负载环，所述负载环具有外径并且位于所述凸起基台的所述第一侧的前方; 围绕负载环的外径安装的卡环。换档工具抵靠换档套筒的第一内肩的动作使得卡环远离负载环移动并且移动到升高的基台的第二侧。
