    摘要： A lateral is gravel packed without a junction in place in a single trip into the wellbore. A disconnect is provided between the isolation packer in the lateral and a main bore packer. The inner string assembly in the gravel packing completion releases a disconnect with a shift tool and then releases the main bore packer so that the inner string assembly takes out the main bore packer and the upper portion of the disconnect when pulling out of the hole. A junction is then placed into the main and lateral legs with a packer having a seal bore into which the production string is sealingly stabbed to produce out of the main bore and/or the just completed lateral.

    摘要翻译： 侧面是砾石填充，没有一个接合处就位，在单次行进到井眼。 在侧面的隔离封隔器和主孔封隔器之间提供断开。 砾石填充完成中的内部柱组件释放与换档工具的断开，然后释放主孔封隔器，使得当拉出孔时，内线组件从主孔封隔器和断开器的上部取出。 然后用具有密封孔的封隔器将连接处放置在主腿和侧腿中，密封孔密封刺入生产线以产生离开主孔和/或正好完成的侧面。
