The specific embodiment
For clearer explanation technical scheme of the present invention, with regard to the specific embodiment the present invention is done further detailed introduction below in conjunction with accompanying drawing.
As shown in Figure 1, U type pipe 11 formula well yield metering devices provided by the invention comprise: the U type pipe 11 of terminal 13, free end sealing.11 liang of free-ended tops of said U type pipe are communicated with through a tracheae 14, and said tracheae 14 is provided with electric control valve 9.Be provided with eddy flow gs-oil separator 2 in the vertical pipeline in the left side of said U type pipe 11, the sidewall of said left side vertical duct is provided with inlet tube flange 1, pressure sensor 10, temperature pick up 12, the liquid-level switch 3 that is connected with the oil well flowline.Said liquid-level switch 3 is selected the capacitance type liquid level switch for use.Said inlet tube flange 1, pressure sensor 10 are positioned at the top of eddy flow gs-oil separator 2, and said temperature pick up 12, liquid-level switch 3 are positioned at the bottom of eddy flow gs-oil separator 2.The bottom of said U type pipe 11 is provided with online analyzer of water content 5.Be provided with liquid level appearance 8 in the vertical pipeline in the right side of said U type pipe 11, the sidewall of the pipeline that said right side is vertical is provided with the outlet flange 6 that is connected with header.Be provided with one way valve 7 on said inlet tube flange 1 and the outlet flange 6.Said liquid level appearance 8, pressure sensor 10, temperature pick up 12, online analyzer of water content 5, liquid-level switch 3, electric control valve 9 all are connected with terminal 13.
Concrete when utilizing metering device according to the invention that oil well yield is measured, the product of oil well output gets into U type pipes 11 through inlet tube flange 1, one way valve 7, and with the product gas-liquid separation, the liquid phase after the separation gets into U type pipe 11 through cyclone gas-liquid separator.The left side vertical duct of U type pipe 11 and the pressure in the vertical duct of right side equate under the electromagnetic gas valve open mode, are in equilibrium state.Liquid level appearance 8 can calculate instantaneous delivery through measuring the liquid level climbing at this moment, and the measurement of process several times just can draw average discharge accurately.The online analyzer of water content of installing in the bottom of U type pipe 11 simultaneously 5 can be measured the profit ratio in the liquid phase.The profit ratio that flow that terminal 13 records according to liquid level appearance 8 and said analyzer of water content 5 record can calculate crude oil yield.
Further, because magnetostrictive liquid level apparatus resolution ratio and precision are all higher, the liquid level appearance 8 described in the present invention adopts magnetostrictive liquid level apparatus, can make metering result's precision higher.
When said liquid level appearance 8 detected liquid level and rises to preset upper limit, terminal 13 sent instruction and cuts out electric control valve 9, and the produced liquid in oil well body enters header through outlet flange 6, one way valve 7 under the oil pumping pump drives.Simultaneously, because the effect of associated gas, the liquid level of the left side vertical duct of U type pipe 11 descends until dropping to liquid-level switch 3 places gradually.In said process, terminal 13 picks up counting when cutting out electric control valve 9, and when said liquid level dropped to liquid-level switch 3, timing stopped; Simultaneously, collect pressure sensor 10, temperature pick up 12 measured force value and temperature value.Terminal 13 promptly can calculate the integrated flux of gas, the i.e. output of gas according to time, temperature, pressure and the equation of gaseous state of timing.Electric control valve 9 is opened the measurement that then gets into next circulation.In the whole measuring process, liquid level sensor, pressure sensor 10, temperature pick up 12, liquid-level switch 3 carry out through automatic alternate cycles under controlling at terminal 13.The one way valve of installing respectively at inlet tube flange 1 and outlet flange 6 places 7 has guaranteed in the metering process that said metering device is relatively independent closed system.
Further; In order to make the temperature in the said metering device be in temperature constant state all the time; The error that reduces to measure, the electric heater that is provided with in the bottom of U type pipe 11 can be controlled at the temperature of output liquid in certain scope, is not merely the raising measuring accuracy and creates conditions; And, can also effectively prevent and produce the wax deposition phenomenon in the pipeline.
Above embodiment is merely preferred embodiment of the present invention, is not the exhaustive of all embodiment of the present invention, so any conspicuous improvement, replacement or the modification on basis of the present invention, made by those skilled in the art all belong to protection scope of the present invention.
