摘要： A technique facilitates pressure containment with a retrievable cement bushing. The retrievable cement bushing includes a body and an engagement lug that cooperates with a sleeve. The engagement lug is mounted on the body and is movable to a radially outward position for engagement with a corresponding portion of a surrounding wall, e.g an internal packer wall. The sleeve is sized to receive a slick joint therethrough and is secured to a radially inward position relative to the engagement lug via a retention member movably mounted on the sleeve, so as to hold the engagement lug in the radially outward position. The sleeve protects the slick joint from inwardly directed loading via the engagement lug when the retrievable cement bushing is subjected to differential pressures.

摘要： A technique facilitates pressure containment with a retrievable cement bushing. The retrievable cement bushing comprises a body having an internal longitudinal passage. Additionally, the retrievable cement bushing comprises an engagement lug which cooperates with a sleeve. The engagement lug is mounted on the body and is movable to a radially outward position for engagement with a corresponding portion of a surrounding wall, e.g an internal packer wall. The sleeve is sized to receive a slick joint therethrough and is movable to a radially inward position relative to the engagement lug so as to hold the engagement lug in the radially outward position. The sleeve protects the slick joint from inwardly directed loading via the engagement lug when the retrievable cement bushing is subjected to differential pressures.
摘要翻译：一种技术有利于用可回收的水泥套管进行压力容纳。可回收的水泥衬套包括具有内部纵向通道的主体。此外，可回收的水泥衬套包括与套筒配合的接合凸耳。接合凸耳安装在主体上并且可移动到径向向外的位置，以与周围壁（例如内部封隔器壁）的对应部分接合。套筒的尺寸被设计成接收通过其的光滑接头，并且可相对于接合突起移动到径向向内的位置，以便将接合凸耳保持在径向向外的位置。当可回收的水泥套管经受差压时，套筒通过接合凸耳保护光滑接头免受向内的负载。
