Abstract
The utility model discloses an on-line metering system for separation of oil, water and gas. A mixed liquid of oil, water and gas enters a first-level separator through a liquid inlet pipe of a separation system. The mixed liquid is mixed sufficiently under the action of natural pressure of the liquid inlet pipe, and then enters a main separator. A gravity rotary chamber is arranged in the main separator and provided with a funnel-shaped cavity, and can rotate around a shaft along the axis of the gravity rotary chamber driven by gravity to separate the mixed liquid of the oil, the water and the gas into a gas phase and a liquid phase and respectively discharge the gas phase and the liquid phase into a gas phase sinking chamber above the gravity rotary chamber and a liquid outlet pipe below the gravity rotary chamber. The gas phase sinking chamber is communicated with a metering room which is used for on-line metering and monitoring of an oil well. Fluids are separated into three states, namely, a gas phase, oil and water after being separated by the separation system. The gas phase can be measured through a gas flow meter while the oil and the water enter the intelligent metering room for analysis and measurement. Flowing pure water volume and pure oil volume can be calculated by entering the density of on-site pure water and pure oil in the metering room so that the function of single measurement of oil production of the oil well can be achieved.
Description
Technical field
The utility model relates to a kind of Oil, Water, Gas and separates online metering system, belongs to the technical field that mixture separation purifies.
Background technology
Oil well on-line metering monitoring system is a part in whole oil data collecting system and the information management system, in the gross mass of measuring demonstration profit gas mixed liquor, flow, density, can extrapolate cumulative water-oil ratio, oil production and gas production.The big problem of error in dipping that bring yet the output liquid that exists in the oil field oil recovery gage work at present contains sand, oil is poor, viscosity is high, oil-gas ratio influences greatly, take out between oil well etc.; Add that oilfield character has nothing in common with each other: extremely oil wells such as heavy oil wells, the high oil well of moisture content, a pumpingh well, oil-gas ratio height are arranged; The part produced liquid in oil well contains accompanying gas hardly; The part sand production is serious simultaneously; Cause the oil field to recover the oil to receive the influence of factors such as oil huge, cause the eliminator liquid level meter of existing Oilfield using normally to use, oval gear flowmeter and duplex rotor meter all also all can't normally measure because of oil and the problem of shaking out; Do not have series of solutions in the prior art, can not satisfy people's requirement.
The utility model content
The purpose of the utility model is to provide a kind of Oil, Water, Gas that can make thoroughly to separate, and makes things convenient for the online metering system of separation of oil well on-line metering monitoring, solves the shortcoming that prior art exists.
The utility model adopts following technical scheme to realize:
A kind of Oil, Water, Gas separates online metering system; This separates gas phase-liquid phase separation that online metering system is used for oil well on-line metering monitoring profit gas mixed liquor; It is characterized in that; Profit gas mixed liquor gets into primary separator through feed tube; Under the natural pressure effect of feed tube, fully mix the laggard eliminator of becoming owner of, be provided with a gravity rotating room in the said main eliminator, said gravity rotating room has the funnel-form cavity and also can rotate from axle at self gravitation its axis of effect lower edge with the pipe internal pressure; The Oil, Water, Gas mixed liquor is separated into gas phase and liquid phase and enters the heavy drain pipe that stays chamber and its below of gas phase of its top respectively, the heavy metrology room UNICOM of staying chamber and oil well on-line metering to monitor of said gas phase.
Further, heavy the staying of said gas phase is provided with the gas phase control valve between chamber and the metrology room.
Further, UNICOM and be provided with the sampling control valve between said metrology room and the drain pipe.
The useful technique effect that the utility model possesses is:
Fluid is separated into gas phase and oil, three kinds of states of water through after separating, and gas phase can be measured through gas flowmeter, and oil and water then get into the intelligent metering chamber and analyzes metering.In metrology room, can calculate pure water amount and the pure oil mass that flows through, realize single amount function the oil well produce oil through the density of importing on-the-spot pure water and pure oil.

Fig. 1 is the overall structure figure that the utility model Oil, Water, Gas separates online metering system.
Fig. 2 is the structural representation of primary separator in the utility model.
Fig. 3 is the cross-sectional view of main eliminator in the utility model.
The specific embodiment
Through facing the description of embodiment down; To help public understanding the utility model more; But can't be regarded as restriction by the concrete embodiment that the applicant is given to the utility model technical scheme, any definition to parts or technical characterictic change and/or to overall structure do form but not the conversion of essence all should be regarded as the protection domain that technical scheme limited of the utility model.
Extremely shown in Figure 3 like Fig. 1; Oil, Water, Gas separates online metering system, and profit gas mixed liquor gets into primary separator 2 through feed tube 1, primary separator 2 and main eliminator 3 UNICOMs; Profit gas mixed liquor gets into primary separator 2 through feed tube 1; Under the natural pressure effect of feed tube, fully mix the laggard eliminator 3 of becoming owner of then, be provided with a gravity rotating room 31 in the main eliminator 3, gravity rotating room 31 has the funnel-form cavity and also can rotate from axle at self gravitation its axis of effect lower edge with the pipe internal pressure; Therefore under cyclonic action; Forms a vortex sheet that rounding is tapered by centrifugal force, gravity and buoyancy in the gravity rotating room 31, the liquid phase that density is big (oil and water) flows to drain pipe 10 along the tube wall of vertical pipe, and the little gas phase of density rises to gas phase along the central authorities of vortex and sinks and stay chamber 4; Here the oil-containing molecule under the effect of gravity, flow back to main eliminator 3 once more divided gas flow get into the heavy chamber 4 of staying of gas phase from the top; Pressure equaliser 6 is used to adjust liquid level and pressure, realizes that the Oil, Water, Gas three-phase fully separates, and gas phase control valve 5 is installed in that gas phase is heavy to be stayed between chamber 4 and the metrology room 7; Between metrology room 7 and the drain pipe 10 UNICOM and be provided with the sampling control valve 8, the exit of drain pipe 10 is provided with discharge opeing control valve 9.Fluid is separated into three kinds of states of gas phase and profit through after separating, and gas phase can be measured through gas flowmeter, and oil and water then get into the intelligent metering chamber and analyzes metering, realizes the on-line measurement of multiphase flow.
Certainly; The utility model can also have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
