| description | The invention discloses an underground oil-water separation layered injection-production pipe column. The problems that an injection system and an extraction system in an existing injection-production pipe column influence each other, and the injection-production pipe column is not suitable for development of a large-liquid-amount same-well injection-production well and a deep-well same-well injection-production well are mainly solved. The device is characterized in that an extraction pump (10) is connected with a sucker rod (12), an injection pump (8) is connected with a submersible cable (13), and the lower end of the injection pump (8) is connected with an oil-water separator (7); the device further comprises a plurality of bottom-hole regulators (17) and injection regulators (4), the bottom-hole regulators (17) correspond to the production layers, and the injection regulators (4) correspond to the injection layers. The injection pump and the extraction pump of the tubular column are driven by two sets of |
