Phase control integrated oil metering separator and oil metering system

This invention disclosed an oil separator and the system. The oil separator consists of at least two phased separators; the separators were connected and there is at least one oil separator and the remaining was storage separator. The system contains computation station and oil separator. The computation includes single well, the transport main and the measure main. The input port connects to the measure main via valve and the output port connects to the transport main. It has a simple structure and works efficiently and precisely. It can be applied to various kinds of wells.
