Detailed description of the invention
In order to clearer explanation technical scheme of the present invention, below in conjunction with accompanying drawing, with regard to detailed description of the invention, the present invention is further described in detail.
As shown in Figure 1, U-tube 11 formula well yield metering device provided by the invention, comprising: the U-tube 11 of terminal 13, free end sealing.The top of described U-tube 11 liang of free ends is communicated with by a tracheae 14, and described tracheae 14 is provided with electric control valve 9.Be provided with eddy flow gs-oil separator 2 in the pipeline that the left side of described U-tube 11 is vertical, the sidewall of described left side vertical duct is provided with the inlet tube flange 1, pressure sensor 10, temperature pick up 12, the liquid-level switch 3 that are connected with oil well flowline.Capacitor hydraulic switch selected by described liquid-level switch 3.Described inlet tube flange 1, pressure sensor 10 are positioned at the top of eddy flow gs-oil separator 2, and described temperature pick up 12, liquid-level switch 3 are positioned at the bottom of eddy flow gs-oil separator 2.The bottom of described U-tube 11 is provided with online analyzer of water content 5.Be provided with tank gage 8 in the pipeline that the right side of described U-tube 11 is vertical, the sidewall of the pipeline that described right side is vertical be provided with the outlet flange 6 be connected with header.Described inlet tube flange 1 and outlet flange 6 are provided with one way valve 7.Described tank gage 8, pressure sensor 10, temperature pick up 12, online analyzer of water content 5, liquid-level switch 3, electric control valve 9 are all connected with terminal 13.
Concrete when utilizing metering device of the present invention to measure oily well yield, the product of oil well output enters U-tube 11 through inlet tube flange 1, one way valve 7, and through cyclone gas-liquid separator by product gas-liquid separation, the liquid phase after separation enters U-tube 11.Pressure under electromagnetic gas valve open mode in the left side vertical duct of U-tube 11 and right side vertical duct is equal, is in equilibrium state.Now tank gage 8 can calculate instantaneous delivery by measuring liquid level climbing, and the measurement through several times just can draw average discharge accurately.The online analyzer of water content 5 simultaneously installed in the bottom of U-tube 11 can measure the profit ratio in liquid phase.The flow that terminal 13 records according to tank gage 8 and the profit ratio that described analyzer of water content 5 records, can calculate crude oil yield.
Further, because magnetostrictive liquid level apparatus resolution ratio and precision are all higher, the tank gage 8 described in the present invention adopts magnetostrictive liquid level apparatus, and the precision of metric results can be made higher.
When described tank gage 8 detects that liquid level rises to preset upper limit, terminal 13 sends instruction and cuts out electric control valve 9, and produced liquid in oil well body, under oil pumping pump drives, enters header through outlet flange 6, one way valve 7.Meanwhile, due to the effect of associated gas, the liquid level of the left side vertical duct of U-tube 11 declines gradually until drop to liquid-level switch 3 place.In above process, terminal 13 timing from during closedown electric control valve 9, until when described liquid level drops to liquid-level switch 3, timer expiration; Meanwhile, pressure sensor 10, force value measured by temperature pick up 12 and temperature value is collected.Namely terminal 13 can calculate the integrated flux of gas according to time of timing, temperature, pressure and equation of gaseous state, i.e. the output of gas.Electric control valve 9 is opened, and enters the measurement of next circulation.In whole measuring process, liquid level sensor, pressure sensor 10, temperature pick up 12, liquid-level switch 3 automatic alternate cycles under terminal 13 is by control is carried out.The one way valve 7 installed respectively at inlet tube flange 1 and outlet flange 6 place ensure that in metering process, and described metering device is relatively independent closed system.
Further, all the time temperature constant state is in order to make the temperature in described metering device, reduce the error of metering, the electric heater arranged in the bottom of U-tube 11 can control in certain scope the temperature of product fluid, be not only raising measuring accuracy to create conditions, and, can also effectively prevent to produce wax deposition phenomenon in pipeline.
Above embodiment is only preferred embodiment of the present invention, and all embodiments of non-invention is exhaustive, so any apparent improvement made on basis of the present invention by those skilled in the art, replacement or modification all belong to protection scope of the present invention.
