The liquid from each oil production well enters the three-phase separator through the liquid inlet pipe of the separator, the volume is increased, the flow rate is reduced, the buffer pressure is reduced, and the gas naturally escapes and floats upwards along with the reduction of the pressure and is discharged through the gas outlet. The gravity settling separation of oil and water is realized by the floating of oil and the sinking of oil under water in the three-phase separator depending on the specific gravity difference of oil and water. The separated oil overflows from the oil weir plate to the oil chamber, water enters the water chamber from the bottom channel through the oil-water interface adjusting device, and the oil, the gas and the water are discharged through an outlet pipeline.
