This invention relates to the field of reservoir development technology and is a co-injection and production tool for CCUS production wells. It includes a tubing string and a cable packer connected sequentially from top to bottom. The cable packer includes an upper connector, a connecting sleeve, an inner central tube, an anchoring assembly, and a lower connector. This invention has a reasonable and compact structure. The cable packer of this application has gas flow channels and liquid flow channels, enabling physical separation and directional flow of gas-liquid two-phase flows under high pressure, thereby achieving co-injection and production and realizing true "in-well circulation": through "downhole separation and co-injection," the separation, reinjection, and storage of carbon dioxide are compressed into a single well, greatly simplifying surface facilities, reducing investment and operating costs, and significantly improving carbon storage efficiency and speed. Through independent gas flow channels and liquid flow channels, efficient separation of gas-liquid two-phase flows can be achieved under high pressure, solving the technical bottleneck of co-injection and production.

This utility model discloses an automatic booster device for oil and gas mixed transportation, including an inlet manifold and a gate valve for the inlet manifold. A first mixed transportation pump group and a second mixed transportation pump group are connected in parallel downstream of the inlet manifold. The first and second mixed transportation pump groups are connected to a common outlet manifold. Downstream of the outlet manifold, an electric heater and a gas-liquid flow meter are connected via pipelines. The first and second mixed transportation pump groups are also connected to a sewage manifold. The second mixed transportation pump group is connected to an emergency tank inlet pump manifold, which is connected to an emergency tank. This device effectively simplifies the equipment and facilities within the station, while significantly reducing station operating energy consumption and safety risks, playing a positive role in promoting the efficient and environmentally friendly development of oil and gas mixed transportation in oilfield surface engineering.

The natural aeration method and device for protecting the valve core of a conical valve belong to the field of high-end water conservancy equipment. The natural aeration method for protecting the valve core of a conical valve comprises the following steps: arranging an annular aeration sill; arranging an aeration hole; the size of the aeration sill is set according to the diameter of the pipeline; the aeration hole is connected with aeration pipes at different levels. The conical valve with the valve core protected by natural aeration comprises the following parts: an aeration sill is arranged on the valve core of the conical valve; the length of the aeration sill is 1 / 4-1 / 6 of the nominal diameter of the valve; the height of the aeration sill is 1 / 10 of the length of the aeration sill; under the arrangement condition, the influence of the aeration sill on the flow capacity of the valve is less than 10%; the beneficial effect of the present application is that the aeration water flow can effectively cover the surface of the valve core after entering the valve body, including the water stop position of the valve seat, and the vibration amount of the valve is significantly reduced.
