To solve the problem of oil and water being unable to be efficiently separated under gas-containing conditions, an integrated cyclone capable of efficiently separating the three phases of oil, gas and water is designed based on the principle of cyclonic separation. Flow field analysis and separation performance study of different treatment amounts, split ratios and oil contents were conducted, and the effects of gas-phase distribution, oil-phase distribution, pressure field and separation efficiency in the cyclone under different conditions were shown. Results indicate that show that the outlet pressure drop, the increase rate and the separation efficiency gradually increase as the processing capacity increases. As the split ratio increases, the oil-phase separation efficiency gradually decreases, and the pressure loss at the bottom flow port gradually increases. The experiment and simulation show that the separation efficiency is the highest when the sum of the internal overflow splits is 50%, and the optimal processing capacity is 23 m 3 /h. The cyclone has a strong adaptability to liquids with different conditions, and the separation efficiency can reach 98.6%.
