  • Patent number: 11708943
    Abstract: A pre-alarming method, a control method, and a control system for a harmful flow pattern in an oil and gas pipeline-riser system are provided. Support vector machines are trained. Through at least three pressure difference signals on the pipeline-riser system, an overall flow pattern in the pipeline-riser system is continuously and rapidly identified. Depending on monitoring on formation of a long liquid slug in a seabed pipeline and a quick response of the mean value of each pressure difference signal on a flow rate change, pre-alarming for a liquid slug caused by different mechanisms is realized, and liquid slug formation positions respectively of seabed pipeline and riser bottom are correspondingly pre-alarmed; after a pre-alarm is issued, there is enough time for a control device to respond, so as to avoid formation of the harmful flow pattern or damages caused by the harmful flow pattern.

  • Publication number: 20220040650
    Abstract: A mixing device for a magnetic bead reagent includes a magnetic member, a container storage mechanism, and a drive mechanism. The container storage mechanism includes a mounting part for mounting a magnetic bead liquid container storing a magnetic bead reagent, and the mounting part corresponds to the magnetic member, enabling the container on the mounting part to be located within the magnetic field. The drive mechanism has a drive structure capable of driving at least one of the magnetic member, the mounting part, and the container to move, and thus generating a relative movement between the container and the magnetic field. The direction of the magnetic force acting on the magnetic beads is changed by the relative movement between the magnetic bead reagent and the magnetic field, such that the magnetic beads flow along different directions under the magnetic force, thereby increasing mixing efficiency of magnetic bead reagent.
