摘要： A valve assembly for wellbore, downhole or intervention operations, such as for subsea wellbore operations includes a rotatable valve member having a passage formed therein. The valve assembly is reconfigurable between a first configuration in which the passage is aligned or alignable with a first conduit, and a second configuration in which the passage is misaligned or misalignable with the first conduit, so as to cut or sever and/or clamp apparatus present in the valve member passage prior to reconfiguration. The assembly is configured to apply a maximum cutting force at a particular phase or stage of the reconfiguration.

摘要： Slug flow of the fluids produced in producing petroleum wells creates major perturbations for production rigs, and leads to major variation in process pressures and levels. In many cases, these perturbations cause unscheduled production stops, and in others may damage equipment such as heat exchangers. Thus slugs have a major impact on the reliability of the operation, as they affect product availability and quality (BSW, TOG and Moisture). Therefore, there exists a complex control problem to use measurements to dynamically act on the production choke valves to set a new type of flow, without major slugs. The object of this invention is to provide an Advanced Automated Control System for minimizing slugs that can quickly act to avoid this type of flow as well as protect the process equipment. This system is comprised of sensors, valves and numerous PID or ONFC type controllers using aggregate computer algorithms to monitor a set of operating variables that enable diagnosing and controlling production well slugs. This advanced control system is efficient and eliminates or minimizes slugs during production well operation.
摘要翻译：生产石油井产生的流体的团状流动造成生产钻井平台的主要扰动，并且导致过程压力和水平的主要变化。在许多情况下，这些扰动会导致计划外停产，并且在其他情况下可能会损坏热交换器等设备。因此，slu have对操作的可靠性产生重大影响，因为它们会影响产品的可用性和质量（BSW，TOG和水分）。因此，存在一个复杂的控制问题，即使用测量值来动态地作用于生产节流阀以设定新的流量，而不会产生大的塞块。本发明的目的是提供一种先进的自动化控制系统，用于最小化可以快速起作用以避免这种类型的流动并且保护处理设备的废料。该系统由传感器，阀门和众多的PID或ONFC型控制器组成，这些控制器使用集合计算机算法来监控一组操作变量，从而可以诊断和控制生产井塞。这种先进的控制系统非常高效，可以在生产井操作过程中消除或减少废料。
