The specific embodiment
Core of the present utility model is to provide a kind of stripper well metering and moisture determinator, comprising: gas-liquid separation mechanism; Connect the volumetric measuring device of described gas-liquid separation mechanism; Connect the Weight metering device of described gas-liquid separation mechanism; Connect the natural gas metering device of described gas-liquid separation mechanism.
As shown in Figure 1, gas-liquid separation mechanism comprises: for carrying out the tank body 11 of gas-liquid separation; The water bag 14 that is arranged on tank base and is communicated with tank body, start metering before, in water bag, to fill with clear water; The gas-liquid separation umbrella 12 and the liquid barrier 13 that are arranged on tank interior, described liquid barrier is positioned at the top of gas-liquid separation umbrella.Tank wall is provided with oil well liquid-producing entrance 17, and described oil well liquid-producing entrance 17 is between gas-liquid separation umbrella 12 and liquid barrier 13.When oil well liquid-producing enters tank body 11 when interior through oil well liquid-producing entrance 17, first through gas-liquid separation umbrella 12, carry out gas-liquid separation, oil-water mixture flows downward in tank body, simultaneously natural gas in tank body on flow, the liquid baffle board that is arranged on oil well liquid-producing entrance top is used for adhering to a small amount of drop containing in natural gas, and this liquid baffle board shape is identical with tank body cross section.
As shown in Figure 1, tank body top is provided with safety valve 15 and the gas outlet 16 that is used for discharging natural gas; Tank wall is provided with the liquid outlet 18 for discharging oil-water mixture, and this liquid outlet 18 is positioned at the top of water bag 14; Tank body 11 bottoms are provided with sewage draining exit 19.
16 places, gas outlet of the present utility model are provided with gas outlet electromagnetic valve 16a; Liquid outlet 18 places are provided with liquid outlet electromagnetic valve 18a; And described gas outlet electromagnetic valve 16a is connected with control device respectively with liquid outlet electromagnetic valve 18a, realize gas outlet give vent to anger and liquid outlet fluid automatically control.
The utility model is measured in tank body the volume of oil-water mixture in particular range by volumetric measuring device, and described volumetric measuring device comprises: interval setting height is arranged on top electromagnetic switch 2a and the bottom electromagnetic switch 2b of tank body 11 inside walls; Connect the control device of described top electromagnetic switch 2a and bottom electromagnetic switch 2b.The preferred top of the utility model electromagnetic switch 2a and bottom electromagnetic switch 2b are float-ball type electromagnetic switch.
By Weight metering device, calculate in tank body the weight of oil-water mixture in particular range, described Weight metering device comprises: the content gauge 3 that is arranged on described tank body 11 lateral walls; The control device being connected with described content gauge; Wherein, described content gauge 3 is communicated with the water bag that is arranged on tank base by communicating pipe 3a.The preferred content gauge 3 of the utility model is magnetic flap level gauge.
By natural gas metering device, calculate gas production, described natural gas metering device comprises: the pressure sensor and the temperature pick up that are arranged on tank body top; The control device being connected with described pressure sensor and temperature pick up.
The utility model control device is preferably PLC controller.By PLC controller, be connected with float-ball type electromagnetic switch, magnetic flap level gauge and pressure sensor and temperature pick up, realize the automatic gauge of stripper well, can disposablely complete the metering of oilwell produced fluid amount, moisture content, oil production and gas production, and by networking, also can be realized teletransmission and automatically be shown, measuring accuracy is higher than the metering device using at present.
The metering process of this stripper well metering and moisture determinator:
Enable device, now PLC controller control gas outlet electromagnetic valve is opened automatically, and liquid outlet electromagnetic valve cuts out automatically, starts a metering cycle.
Open the valve of oil well liquid-producing entrance simultaneously, oil well liquid-producing enters tank body from oil well liquid-producing entrance, first passes through gas-liquid separation umbrella, and oil-water mixture relies on gravity to flow downward in tank body, simultaneously natural gas in tank body on flow, through liquid baffle board, flow to gas outlet.
Along with constantly entering of oil well liquid-producing, the liquid level of oil-water mixture in tank body rises gradually, and when the liquid level of oil-water mixture in tank body rises arrival bottom float-ball type electromagnetic switch, PLC controller starts timing and control magnetic flap level gauge to start metering.When liquid level rises arrival top float-ball type electromagnetic switch, PLC controller stops timing and controls magnetic flap level gauge stopping metering, and gas outlet electromagnetic valve cuts out automatically simultaneously, and liquid outlet electromagnetic valve is opened automatically, oil-water mixture is discharged from liquid outlet, complete a metering cycle.
After completing, discharge opeing can automatically start next metering cycle.
When this utility model is used for stripper well, the time of metering cycle can reach several hours to a few hours according to oil well output difference, thereby overcome well section plug flow and the fuel-displaced measurement deviation causing at intermittence, its measuring accuracy far exceedes current various metering methods, and measures easy.
Measuring principle is as follows: because the distance between top float-ball type electromagnetic switch and bottom float-ball type electromagnetic switch for measuring volume is a known constant, the time interval that PLC controller can open or close according to upper and lower float-ball type electromagnetic switch is calculated the oil-water mixture volume between top float-ball type electromagnetic switch and bottom float-ball type electromagnetic switch.Measuring in volume, PLC controller control magnetic flap level gauge is measured, measurement be the water-column from water bag, PLC controller calculates the weight of the oil-water mixture that volume is known according to the proportion of water.Owing to there being the oil-water mixture proportion of different volumes and weight in PLC controller, according to the oil-water mixture volume and the weight that have recorded, can conveniently calculate stripper well oil production and moisture content.
The discharge of the utility model oil-water mixture, is by closing after the electromagnetic valve of gas outlet, and the gas pressure of generation is realized.Therefore, requiring very not strict in the situation that, can to calculate gas production according to the efflux time of oil-water mixture.Concrete principle is as follows: by the pressure sensor and the temperature sensor measurement that are arranged on tank body, draw tank body pressure and temperature, PLC controller, according to tank body pressure and temperature, oil-water mixture efflux time, calculates gas production.
This stripper well metering and moisture determinator be operation automatically under the control of PLC controller, convenient management, and cheap, safeguard simple.The utility model, when individual well is used, is closed gas outlet electromagnetic valve, from sewage draining exit, discharges free water, and with gas pressure in tank body, complete individual well and draw oily automatic loading, during self gas deficiency, can a standby mini gas pressurized tank.When the utility model is applied in cluster well group, also can coordinate with the metering of storage tank magnetic turnover panel, monitor other oil well output, realize the long-time gauging of individual well, improve measuring accuracy.
Although above the utility model is explained in detail; but the utility model is not limited to this; those skilled in the art can modify according to principle of the present utility model; therefore, all various modifications of carrying out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
