The invention discloses a real-time regulated downhole gas-liquid separation combination lift system capable of being suspended. The system includes an oil tube connected to a suspended three-way assembly, a jet-pump lift system is arranged in the suspended three-way assembly, an electric-pump lift system assembly is suspended at a first port of the lower end of the suspended three-way assembly, and a gas-liquid separation system assembly is connected to a second port of the lower end of the suspended three-way assembly through a gas-collection oil tube; the system further includes a flow control valve and a visual control device; the visual control device is connected with the electric-pump lift system assembly, the gas-liquid separation system assembly and the flow control valve. By the adoption of the electric-pump and jet-pump combined lift system, no external high-pressure power liquid is needed, high-pressure liquid-rich flow which flows through the electric pump serves as power liquid to suck separated gas-rich flow, and then the separated gas-rich flow is lifted to a wellhead, so that downhole gas-liquid separated exploitation is achieved. By the adoption of the real-time regulated downhole gas-liquid separation combination lift system capable of being suspended, the application of a conventional electric pump in an oil well with a high gas-liquid ratio is achieved, and the application range of the conventional electric pump in the oil well with the high gas-liquid ratio is broadened.
