Low-carbon energy utilization system for steam and power cogeneration of oil field

A low-carbon energy utilization system for steam and power cogeneration of an oil field, wherein the low-carbon energy utilization system comprises:

• a first water pump device;
• a second water pump device;
• electric heating devices connected to the first water pump device, each of the electric heating devices is used for receiving and heating first water output by the first water pump device, and outputting the first water after being heated and first steam;
• a liquid mixer connected to the second water pump device and the electric heating devices, wherein second water that is output by the second water pump device and the first water after being heated, which is output by each of the electric heating devices, are entered into the liquid mixer;
• and the second water and the first water after being heated are output by the liquid mixer;
• a fossil-fuel steam injection boiler connected to the liquid mixer, the fossil-fuel steam injection boiler is used for receiving the second water and the first water after being heated, which are output by the liquid mixer;
• and the fossil-fuel steam injection boiler is further used for generating and outputting second steam;
• a steam mixer connected to the electric heating devices and the fossil-fuel steam injection boiler, wherein the first steam that is output by each of the electric heating devices and the second steam that is output by the fossil-fuel steam injection boiler are both entered into the steam mixer and are output by the steam mixer;
• a super-heater connected to the steam mixer, the super-heater is used for receiving third steam output by the steam mixer, the super-heater is used for heating the third steam to be required high-temperature and high-pressure steam, and conveying the required high-temperature and high-pressure steam to an oil well;
• a new energy generation station, the new energy generation station is used for supplying power to the electric heating devices;
• and
• wherein a steam-liquid separation device is arranged in the steam mixer.
