Examples
Embodiment 1
[0028] The degassed well fluid enters the oil-water separation tank 1 from the degassed oil liquid input port 5. When the degassed well fluid in the oil-water separation tank 1 reaches the set standard, the valve of the degassed oil liquid input port 5 is closed, and the oil, water, Oil sludge is preliminarily separated by sedimentation, and the pressure machine 3 is opened to increase the air pressure in the oil-water separation tank 1. Under the action of pressure, oil, water, and oil sludge are further separated.
Embodiment 2
[0030] The control box 16 adjusts the voltage to the transformer 4, and outputs the voltage to the positive electrode plate 6 and the negative electrode ring electrode plate 7 through the wires, so that an electrostatic field space is formed between the positive electrode plate 6 and the negative electrode ring electrode plate 7, and the positive electrode plate Oil is separated from water within the electrostatic field of plate 6 and negative ring electrode plate 7 .
Embodiment 3
[0032] The upper pressure sensor 10 measures the upper pressure value in the oil-water separation tank 1, the lower pressure sensor 14 measures the lower pressure value in the oil-water separation tank 1, the upper pressure value and the lower pressure value are transmitted to the adapter module 17 through wires, and the adapter module 17 After the pressure value signal is converted, it is input to the central computer 18, and the central computer 18 calculates the pressure difference between the upper and lower sides of the oil-water separation tank 1, and obtains the position of the oil-water interface in the oil-water separation tank 1, and adjusts the pressure machine 3 so that the oil-water interface is located in the electrostatic field space of the middle.
