The invention belongs to the field of offshore oil and gas field development, and in particular relates to a deep-sea multiphase and multistage separation reinjection system. Deep-sea multi-phase multi-stage separation and reinjection system includes: overall support structure, vertical separator, gas-liquid cyclone separator, coil liquid-liquid separator, buffer tank and booster reinjection pump, of which: vertical Separator, gas-liquid cyclone separator, coil type liquid-liquid separator, buffer tank and booster recharge pump are located in the overall support structure, vertical separator, gas-liquid cyclone separator, coil type The liquid-liquid separator, buffer tank and booster refill pump are connected in sequence. The oil well production fluid of the present invention is directly subjected to multiphase separation in it, avoiding lifting the water contained in the production fluid to the platform and occupying valuable platform area, which can save a lot of energy for deep sea areas, especially wells with high water cut At the same time, the static pressure of the standpipe and the back pressure of the wellhead are greatly reduced, and the risks of pipeline leakage and deformation are reduced, which is conducive to the stability of production.

The invention relates to a deepwater seabed oil and water separation and reinjection device which comprises a base platform, an upper support, a lower support, a separator, a buffer tank and a booster reinjection pump. The separator, the buffer tank and the booster reinjection pump are arranged on the base platform; a rear gas outlet pipeline of the separator is mounted on the top of the rear of the separator; the buffer tank is close to a water outlet pipeline of the separator, the booster reinjection pump is close to an inlet pipeline of the separator, the water outlet pipeline of the separator is connected with the buffer tank and extends into the buffer tank, the buffer tank is connected with the booster reinjection pump by an outlet pipeline of the buffer tank, and the booster reinjection pump drains boosted water via an outlet pipeline. The deepwater seabed oil and water separation and reinjection device has the advantages that the device is mounted in deep sea water, produced liquid of wells does not need to be lifted to an offshore platform to be processed, accordingly, occupation of precious platform areas can be prevented, and a large quantity of energy can be saved for the oil wells positioned on seabed at the depth of thousands of meters; static pressures of risers and back pressures of wellheads can be greatly lowered, risks of pipeline leakage, deformation and the like can be reduced, and the deepwater seabed oil and water separation and reinjection device is favorable for stabilizing production.
