Technical Field

The invention relates to the technical field of data processing, in particular to a method and a device for determining the running state of a three-phase separator.

Background

The oil gas gathering and transferring system covers a gathering and transferring pipe network and an oil field station warehouse. The gathering and transportation pipe network is used for gathering the produced liquid of a single well to a station warehouse such as a united station. The combined station is generally composed of an oil station, a sewage station and a water injection station. The oil station mainly comprises three-phase separators, an oil unloading device, an outward conveying pump, a dryer and other equipment, the treated sewage is conveyed to a sewage station, the natural gas is conveyed to a natural gas treatment station through a pipe network, and the crude oil is pressurized, heated and metered and then is conveyed outward.

The crude oil passes through the oil-gas separator and the oil-gas-water three-phase separator, so that the crude oil can be simply separated, and a certain foundation is laid for further processing, refining and purifying the crude oil. The three-phase separator is used for separating gas, solid and liquid phases, and comprises a mud bin and a water bin which are connected up and down to form a whole. The mud bin is formed by combining a cylinder body, an air inlet/outlet, a filtering component, an end enclosure, a mud discharging device, a water outlet and an inlet hole, and the water bin is formed by a box plate, a bottom plate, a partition plate, a water outlet, a ventilation port, an inlet hole and the like. The three-phase separator has the advantages of simple structure, small occupied area, reliable operation, zero energy consumption, capability of automatically completing the separation process and the like, and is suitable for gas, liquid and solid three-phase separation, particularly gas, liquid and solid three-phase separation with high solid content and great flow conversion. Oil-gas-water three-phase separators are the most common equipment used in the development of most oil fields.

However, in the real production process, the three-phase separator has irreplaceable significance for oil-water-gas separation in an oil field gathering system, and meanwhile, the larger pressure has certain generation danger. In real production, it is not possible to verify the best regulation scheme and to verify the safety reserve time by adjusting all combinations of the relevant valves of the three-phase separator when pressure or flow variations occur. That is, the use of the three-phase separator in the related art has a safety hazard.

Aiming at the problem that potential safety hazards exist in the oil-water-gas separation process of the oil field gathering and transportation system by using the three-phase separator in the related technology, an effective solution is not provided at present.
