Description
One, technical field: the utility model relates to a kind of measurement of flow, relates in particular to the continuous metering device of a kind of gas and oil-water mixture flow.
Two, background technology: a kind of oilwell produced fluid amount measuring apparatus of using in the oil exploitation at present is a separation vessel, and it is made of shell, the diffusing oily cap of umbrella formula, liquid level display tube and metering scale etc., its objective is the liquid measure that is metered into separation vessel.The separation vessel measuring apparatus of this structure has been subjected to user's welcome in a period of time, but along with the development of oil development and the formation of market economy, the oil well output accuracy also needs thereupon day by day, because there is following shortcoming in the separation vessel metering, therefore very is an impediment to the accurate metering of profit gas:
1, because separator designs pressure is low, be 1.6MPa only, under the higher situation of ductwork pressure, just can not normally measure,
2, the lower or viscous crude producing region at oil-gas ratio, separation vessel liquid level can not depress, or just can depress for a long time under the next situation, cause and can not measure or can not in time measure;
3, because the separation vessel gauging only measures gauging time period oil well yield, and the output of whole day then convert, therefore exist head the inaccuracy of measuring.
Three, summary of the invention: the purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of under any circumstance all that can measure and continuous metering device accurate measurement is provided.
Its technical scheme is: a kind of continuous metering device, comprise liquid-level controller (LLC) and connected gas-liquid flowmeter, the shell inner cavity of its liquid-level controller (LLC) is settled floating ball device and centralizer, device upper valve base and gas connection pipe on the gas vent that is provided with on the flange of shell upper end, connect gas meter on it, the profit outlet that is provided with on the end flanges under the shell is gone up lower valve base and liquid connecting pipe is installed, and connects liquid flowmeter on it.
Floating ball device comprises float and the upper and lower valve ball that is connected its two ends, matches with last lower valve base respectively.One end of centralizer is fixed on the inwall of shell, and the other end is a roller, and rolling with the outer wall of float contacts.Float is the hollow circuit cylinder body structure of sealing, and its outer wall rolls with centralizer and contacts.Gas flow is counted the commercially available prod, and fluid flow is counted the smart electronics flowmeter that Zhejiang temperature automation equipment company limited produces, but also can change other products according to user's needs.
The utility model has following advantage and beneficial effect compared with prior art:
1, accuracy of measuring height can reach 0.5%-1.0% to the oil-water mixture accuracy of measuring that does not conform to gas;
When 2, the utility model not only can measure wink flow, and can measure and show total flow and accumulative total total flow on the same day, also can show the daily fluid production rate of any given day, realize comprehensive dynamic monitoring of oil well;
3, the utility model design pressure height be 3.5MPa, and the pipe oil separator of prior art is 1.6MPa, and having solved that because of the main line back pressure high and oil well is narrow-minded can not gauging and influence the problem of gauging;
4, improved the accuracy of oil-gas ratio in the daily data admission, in the continuous measurement liquid measure, also measure tolerance, also can calculate the oil-gas ratio and the oil yield of each individual well according to the water percentage of output liquid exactly, for the management and the analysis of oil well provides reliable foundation;
5, adopted the smart electronics flowmeter, can accurately and timely monitor the intermittently quiescent interval of producing well, found out intermittently rule, for the development management of these wells provides important data to guarantee;
6, improved automatic management level, realized man-machine separation to greatest extent, monitor without the special messenger during gauging operation, the time of metering is changeable, even forgotten also and any problem can not take place, and easy and simple to handle, alleviated labor intensity of operating personnel greatly, also alleviate the production line personnel simultaneously and lacked general contradiction.
7, the utility model can accurately and timely be followed the tracks of the situation of change of the output after the oil well measure continuously, washes, transfers ginseng, bumps the output recovery situation Isoquant Changing Pattern behind pump and the inspection pump, for later measure provides reliable basis such as heat;
8, the utility model also can be assembled into the mobile measuring apparatus of vehicular, has solved and has directly advanced the main line oil well, and the series connection well does not stop the independent measurement problem of well; Also can satisfy prospect pit, new well is asked the needs of product continuously.
Four, description of drawings:
Fig. 1 connects the flowage structure synoptic diagram for the utility model continuous metering device;
Fig. 2 is the liquid-level controller (LLC) structural representation.
Five, embodiment: consult Fig. 1 and Fig. 2, a kind of continuous metering device, comprise liquid-level controller (LLC) 3 gentle flowmeters 4, liquid flowmeter 6, shell 36 inner chambers of liquid-level controller (LLC) 3 are settled floating ball device 33,35,37 and centralizer 39, device upper valve base 38 and gas connection pipe 9 on the gas vent that is provided with on the flange 310 of shell upper end, connect gas meter 4 on it, the profit outlet that is provided with on the end flanges 311 under the shell is gone up lower valve base 34 and liquid connecting pipe 10 is installed, connect liquid flowmeter 6 on it, this flow is counted the smart electronics flowmeter.Connect filtrator 2 on the oil gas water inlet, the other end of gas meter 4 and smart electronics flowmeter 6 is connected with oil gas water mixed liquid outlet 7 by connecting pipe 8, and the emptying of installation gas 5 on the connecting pipe 8.Float connects upper valve ball 37, lower valve ball 35, and matches with last lower valve base 38,34 respectively.Float 33 is the hollow circuit cylinder body structure of sealing, and its outer wall rolls with centralizer 39 and contacts.One end of centralizer 39 is fixed on the inwall of shell 36, and the other end is a roller, and rolling with the outer wall of float 33 contacts.On the gas vent that is provided with on the flange 310 of shell 36 upper ends, install valve seat 38 and gas connection pipe 9, connect gas meter 4 on it.Lower valve base 34 and liquid connecting pipe 10 are installed on the liquid outlet that is provided with on the following end flanges 311 of shell 36, are connected liquid flowmeter on it, this flow is counted the smart electronics flowmeter.When the utility model was used, under the original state, float 33 was because action of gravity, and 35 of lower valve balls have been closed liquid outlet on lower valve base 34.At this moment, top valve ball 37 breaks away from upper valve base 38, opens gas vent, and gas is mouthful discharge thus, measures gas flows through gas connection pipe 9 by gas meter 4; After liquid level rises to certain position, liquid buoyancy is during greater than float 33 gravity, and float rises, and gas vent is closed, liquid outlet is opened, oil-water mixture by smart electronics metering meter 6 metering back, enters pipe network through escape hole 7 through liquid connecting pipe 10 again, this moment, liquid-level controller (LLC) 3 interior liquid levels constantly made float 33 descend under the effect of upper gas, greater than liquid buoyancy, liquid outlet is closed once more until the gravity of float, so circulation.When old well did not have associated gas or associated gas very little, float will cut out gas vent under the effect of liquid buoyancy all the time, at this moment can only oil-water mixture flowed out and measured by the electronic smart meter flowmeter from liquid outlet.What of gas do not influence normal use of the present utility model.
