Abstract
The utility model provides a multiphase flow measuring system. The multiphase flow measuring system comprises a gas-liquid separator (1), an electromagnetic valve (2) and an oil-water ratio resolving device (4), wherein the electromagnetic valve (2) is connected with the gas-liquid separator (1) through pipelines, the oil-water ratio resolving device (4) is connected with the gas-liquid separator (1) through a pipeline and is an annular capacitor, and the annular capacitor comprises an annular inner electrode (4-1) and an annular outer electrode (4-2). The multiphase flow measuring system has the advantages of being capable of continually measuring fluid, monitoring flow of oil, gas and of water in real time, and ensuring that policy-making bodies can master off-take potential of each well in real time.
Description
Technical field
The utility model relates to a kind of multiphase flow metering system, belongs to the oil measurement technical field.
Background technology
Present multiphase flow metering system can only at use for laboratory, can not be generalized to on-the-spot the use.A kind of multiphase flow metering system of my unit utility model, on-the-spot continuous, Real Time Monitoring again.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of multiphase flow metering system is provided.
Multiphase flow metering system of the present utility model, the electromagnetic valve (2) that comprises gas-liquid separator (1), is connected with gas-liquid separator (1) by pipeline, the oil-water ratio resolving device (4) that is connected with gas-liquid separator (1) by pipeline, described oil-water ratio resolving device (4) is ring-plate capacitor, described ring-plate capacitor comprises interior electrode (4-1) and the external electrode (4-2) of annular, described ring-plate capacitor surface scribbles glass, and described ring-plate capacitor is connected non-conducting materials such as adopting nylon with pipeline.Also be connected with differential pressure pick-up (3) by pipeline on gas-liquid separator (1), be used for controlling the liquid level in gas-liquid separator (1).The entrance of oil-water ratio resolving device (4) or the port of export are connected to fluid flowmeter (5), are used for calculating the flow of oil phase and water.The entrance of electromagnetic valve (2) or port of export incoming gas flow amount meter (6) are used for the metering gaseous fluid.
Multiphase flow metering system of the present utility model has following technique effect:
1, can the continuous measurement fluid;
2, can Real Time Monitoring oil, the flow of gas, water, make policy-making body can grasp in real time every mouthful of well capacity.
Description of drawings
Fig. 1 is the structure chart of multiphase flow metering system of the present utility model;
Fig. 2 is the structural representation of ring-plate capacitor.
Wherein, 1 is gas-liquid separator, and 2 is electromagnetic valve, and 3 is differential pressure pick-up, and 4 is the oil-water ratio resolving device, and 5 is fluid flowmeter, and 6 is gas flowmeter, and 4-1 is interior electrode, and 4-2 is external electrode.
The specific embodiment
As shown in Figure 1, the electromagnetic valve (2) that multiphase flow metering system of the present utility model comprises gas-liquid separator (1), is connected with gas-liquid separator (1) by pipeline, the oil-water ratio resolving device (4) that is connected with gas-liquid separator (1) by pipeline, described oil-water ratio resolving device (4) is ring-plate capacitor, described ring-plate capacitor comprises interior electrode (4-1) and the external electrode (4-2) of annular, described ring-plate capacitor surface scribbles glass, and described ring-plate capacitor is connected non-conducting materials such as adopting nylon with pipeline.Also be connected with differential pressure pick-up (3) by pipeline on gas-liquid separator (1), be used for controlling the liquid level in gas-liquid separator (1).The entrance of oil-water ratio resolving device (4) or the port of export are connected to fluid flowmeter (5), are used for calculating the flow of oil phase and water.The entrance of electromagnetic valve (2) or port of export incoming gas flow amount meter (6) are used for the metering gaseous fluid.
Multiphase flow metering system of the present utility model is in when work, environment temperature-100 ℃, and operating pressure 0-10MPa can be used for the metering that flow is 1-100m3, and measuring accuracy is 2%.Oil-water ratio resolving device 4 adopts capacitance method, utilizes the different dielectric constant of profit, and oil-water mixture can calculate the ratio value of profit amount jointly accurately by the measured capacitance of annular capacitor pipe.Total liquid measure is calculated by indicator card by the oil well that the power sensor is housed, for the oil well that does not fill the power sensor, need to install a fluid flowmeter 5, ring-plate capacitor is designed to the inside-and-outside ring structure, tested profit can accurately be tried to achieve the ratio of profit during by ring-plate capacitor, the ring-plate capacitor surface scribbles glass, make its surface nature hydrophilic, the insulation, inner and outer pipes all uses electric-heating constant temp. device.
