摘要： Systems and methods are provided for supplementing existing management methods for and corroborating condition and performance of a blow out preventer for a submerged well. The corroborator is located on the blow out preventer and includes a flow meter external to a pipe to measure flow inside the pipe, a pipe joint locator, a ram seal confirmation agent, a dedicated communication connection from the corroborator to a computer topside. Data from at least one sensor topside, which may represent a mud tank level, is also received. The computer is enabled to calculate a probability that a malfunction related to the well occurs. The computer may be configured to implement a Principal Component Analysis model of the well based on historical data, to assess a likelihood that a threshold value will be surpassed based on collected sensor data and to generate an alert. The computer implements instructions to perform steps of the present invention.
摘要翻译： 提供了系统和方法，用于补充现有的管理方法，并确定浸没井的防喷器的状态和性能。 确认器位于防喷器上，包括管道外部的流量计，用于测量管道内的流量，管接头定位器，压头密封确认剂，从校准器到计算机顶部的专用通信连接。 还接收来自至少一个传感器顶部的数据，其可以代表泥浆罐水平面。 计算机能够计算与井相关的故障发生的概率。 计算机可以被配置为基于历史数据实现井的主成分分析模型，以评估基于收集的传感器数据将超过阈值并产生警报的可能性。 计算机实现执行本发明的步骤的指令。
