摘要： A wellhead completion assembly has a head connected to surface casing. A rotatable flange or the like can be used to connect various components to a threaded end of the head. A casing hanger installs in the head, and the hanger's upper end extends beyond the head's top edge. This exposed end has an external threaded connection to connect to various wellhead components using a rotatable flange or the like. For example, a locking ring can threadably connect to the head's threaded end to support the hanger in the head. Then, a rotatable flange can threadably connect to the hanger's exposed end so that another component, such as a completion spool or gate valve, can nippled up directly to the hanger. When the hanger is fluted, a pack-off assembly can allow testing off inner and outer sealing integrity via a test port accessible through an opening in the locking ring.

摘要翻译： 井口完井组件的头部连接到表面套管。 可以使用可旋转的凸缘等来将各种部件连接到头部的螺纹端。 衣架安装在头部，衣架的上端延伸到头顶部边缘之外。 这个暴露的端部具有外部螺纹连接，以使用可旋转的凸缘等连接到各种井口部件。 例如，锁定环可以螺纹连接到头部的螺纹端部以支撑头部中的衣架。 然后，可旋转的凸缘可以螺纹连接到悬挂器的暴露端，使得诸如完成阀芯或闸阀的另一部件可以直接地接合到悬挂器。 当衣架有凹槽时，包装组件可以允许通过可通过锁定环中的开口接近的测试端口来测试内部和外部的密封完整性。
