[0002] Currently, most oilfields are operating at a very high water content stage, with produced fluids typically exceeding 80% and sometimes as high as 95%. This produced fluid not only contains high water content but also gas and sand particles. Therefore, separation of oil, gas, water, and sand, as well as wastewater treatment, has always been a technical challenge for gathering and transportation systems. To ensure annual crude oil production, the total volume of produced fluids from oilfields is increasing significantly year by year, exceeding the original design capacity of the combined stations. Tank operations must be shut down in spring and autumn for sand removal, directly impacting crude oil production. Furthermore, due to crude oil's high density, viscosity, low gas-to-oil ratio, and sand-induced foaming, separation of oil, gas, water, and sand, as well as wastewater treatment, is even more challenging at low temperatures. In recent years, oilfields have invested heavily in expanding heating furnaces to increase the temperature of produced fluids, resulting in increasing operating costs and management difficulties.
