    Abstract: A subsurface safety valve features vertically stacked springs that are each independently supported in the valve housing and each having an opposite end that bears on a shoulder connected to the flow tube. When mounted this way their applied force is additive as they are in effect mounted in parallel between the housing and the flow tube for overcoming hydrostatic pressure in deep set applications that can exceed 20,000 feet. The stacking also allows the cross-sectional area of the flow tube to be maximized for a given housing outside diameter dictated by well conditions.

    Abstract translation: 地下安全阀具有垂直堆叠的弹簧，其各自独立地支撑在阀壳体中，并且每个具有支撑在与流管连接的肩部上的相对端。 当以这种方式安装时，它们的施加的力是相加的，因为它们实际上平行地安装在壳体和流动管之间，以克服超过20,000英尺的深层应用中的静水压力。 对于由井条件规定的给定外壳外径，堆叠还允许流管的横截面面积最大化。

    Abstract: A system is provided for switching between redundant control systems for a subsurface safety valve (SSV) while being able to isolate the closure spring from hydrostatic pressure in the control line of the system that is not being used. There are two control lines that connect to discrete operating pistons that are both coupled to the flow tube. Each operating piston is connected to a control rod with the control rods terminating near opposed ends of a pivoting member. Pushing down on one rod pushes up on the other rod so that the other rod is held supported and the hydrostatic pressure in its associated control line doesn't affect the force needed by the closure spring to close the SSV. Releasing control line pressure puts the system in neutral to allow either of the systems to be reselected.

    Abstract translation: 提供了一种用于在地下安全阀（SSV）的冗余控制系统之间切换的系统，同时能够将闭合弹簧与未使用的系统的控制线中的静水压力隔离开。 有两条连接到离散的操作活塞的控制线都连接在流管上。 每个操作活塞连接到控制杆，控制杆在枢转构件的相对端附近终止。 将另一根杆推到另一根杆上，将另一根杆保持在支撑状态，其关联控制线中的静水压力不会影响闭合弹簧关闭SSV所需的力。 释放控制线压力使系统处于中立状态，以允许任何一个系统被重新选择。

    Abstract: A threat propagation estimator generates threat propagation estimates for a region based on a combination of sensor data (z) and model-based threat propagation estimates. The threat propagation estimator receives sensor data (z) from one or more sensor devices, and employs threat propagation model (M) to generate a model-based threat propagation estimate. A threat propagation algorithm (20) is used to combine the sensor data (z) and the model-based threat propagation estimate to generate a threat propagation estimate (Jc ).
