    • A through tubing bridge plug is disclosed. In the preferred and illustrated embodiment, a central hollow tube having a passage therein supports the external parts. The central passage terminates top and bottom with openings or passages. At the top end, a sleeve valve mechanism originally pinned in an open position is installed. When the installation is completed, the sleeve valve is closed by a sequence of operations to permanently close the flow path. The device is set and anchored by applying a relative downward force to an external sleeve thereby deploying multiple link toggle means to lock the device in location, additionally deploying a upwardly facing petal basket to receive a charge of sand and cement to form a plug, and also deploying a centralizer. The device is installed at a specified elevation by anchoring the toggle means to prevent movement, deploying the petal basket to hold sand and cement for curing, locating the device in the casing by a centralizer, and bypassing fluid around the curing sand and cement through a central tubing opening below and above the uncurred materials. The final step includes closing a sleeve valve means to prevent further flow through the device.
    • 公开了一种通过管道桥塞。 在优选和示出的实施例中,具有通道的中心中空管支撑外部部件。 中央通道以顶部和底部终止于开口或通道。 在顶端安装一个最初固定在打开位置的套筒阀机构。 当安装完成时,套筒阀被一系列操作关闭,以永久关闭流路。 通过将相对向下的力施加到外部套筒来设置和锚定该装置,从而部署多个连杆肘节装置以将装置锁定在位置,另外展开向上的花瓣篮以接收沙子和水泥的装料以形成塞子,以及 还部署了一个扶正器。 该装置通过锚定肘节装置来安装在特定的高度,以防止移动,展开花瓣篮以保持沙子和水泥进行固化,通过扶正器将装置定位在套管中,并通过一个围绕固化砂和水泥的流体旁路流体 中心油管开口低于和高于未燃料。 最后一步包括关闭套筒阀装置以防止进一步流过装置。

    • An umbrella unit which is screwed to an actuating tool and lowered into the production tubing of an oil well by means of a wire line is fitted with a set of upwardly directed and a set of downwardly directed spring-actuated knives which are outwardly and radially displaceable within the well casing so as to lock said umbrella against the casing wall in the required plugging position, the umbrella proper being then caused to open out radially and filled with gravel or like material. A spoon comprising a reservoir tube filled at the wellhead with cement grout is lowered by means of a wire line, the cement grout being discharged through bottom openings by means of a glass window which is broken by means of a striker piece upon impact of the bottom of the spoon on the gravel.
