Processing capacity evaluation method and device for oil field joint station, monitoring method of processing capacity evaluation method and monitoring system

The invention discloses a processing capacity evaluation method and device for an oil field joint station, a monitoring method of the processing capacity evaluation method and a monitoring system. Theprocessing capacity evaluation method is characterized in that according to parameters of an input device and parameters of each output device of the oil field joint station, the maximum input capacity of the input device of inputting the crude oil production fluid into the oil field joint station is determined, the maximum output capacity of each output device of outputting the output medium tothe oil field joint station is determined, based on the mass conservation principle, a processing capability model of the oil field joint station is established based on the maximum input capacity andthe maximum output capacity, and the used processing capacity and the remaining processing capacity of the oil field joint station can be determined by the processing capability model based on the amount of crude oil productio
