摘要: An additional string is run through an existing string using a running string. With the strings overlapping an upper inflatable secures them together leaving gaps. The upper inflatable creates an upper expanded zone where the swage assembly is then built. The swage assembly has a seal and upon pressure being applied between the upper inflatable and the seal the swage assembly releases the running string and is pushed to expand the additional string until tagging a cement shoe. The running string is rejoined to the swage assembly and after cementing a lower inflatable is deployed to make a bell and to set an external packer if used. If there is an external packer the shoe releases and on the way out of the hole the upper inflatable sets a seal in the lap.
摘要翻译: 一个额外的字符串通过使用运行字符串的现有字符串运行。 如果绳子重叠,则上部充气可将它们固定在一起,留下间隙。 上部充气产生一个上部扩展区域,然后构建模具组件。 挤压组件具有密封件,并且在上部可充气和密封件之间施加压力时,模具组件释放运行的排,并被推动以扩展附加的柱直到标记水泥鞋。 运行的绳子被重新连接到挤压组件,并且在固定之后,部署下部可充气以制造钟形并且如果使用则设置外部封隔器。 如果有一个外部封隔器,鞋子释放,并且在出口的路上,上部充气器在圈中设置密封。
