Xiamen Hongkong Instrument Engineer will explain to you: the application of mass flow meter in oilfield well measurement.
With the development of oilfields entering the middle and late stages, the characteristics of large fluctuations in oil well production and rising water cut make the traditional volumetric flowmeter and velocity flowmeter have a large measurement error in the measurement process. In order to improve the accuracy and reliability of well metering, more and more oil fields have begun to adopt mass flow meters for well metering. This article will review the application of mass flow meter in oilfield well metering.
First, the working principle of the mass flow meter.
A mass flow meter is a flow meter based on the Coriolis principle that is capable of directly measuring the mass flow of fluids. In a mass flow meter, when a fluid passes through a measuring tube, it is subjected to a Coriolis force, which is proportional to the mass flow rate of the fluid. By measuring the magnitude of the Coriolis force, the mass flow rate of the fluid can be calculated.
2. Advantages of mass flow meter in oilfield well metering.
1.Direct measurement of mass flow.
The mass flow meter can directly measure the mass flow rate of the fluid, which is not affected by the fluid density, temperature, pressure and other factors, so it has high measurement accuracy and reliability.
2.Wide measuring range.
The mass flow meter has a wide measurement range, which can adapt to the metering needs of oil wells with different liquid production volumes. At the same time, through reasonable selection and installation, multiple oil wells can be measured at the same time.
3.High degree of automation.
The mass flow meter can realize automatic measurement and control, can monitor the production of the oil well in real time, and upload the measurement data to the oilfield management system through the data transmission system, which is convenient for production management and data analysis.
4.Easy to maintain.
Mass flow meters are simple in structure, easy to maintain, and do not require complex calibration and adjustment in daily use. At the same time, it has a long service life and can adapt to the needs of long-term production in the oilfield.
3. Application examples of mass flow meters in oilfield well metering.
There are a total of 100 oil wells in an oilfield, and the liquid production fluctuates greatly and the water cut is high. In order to improve the accuracy and reliability of oil well metering, the oilfield decided to use the HK-CMF mass flow meter produced by Xiamen Hongkong Automation Instrument *** for oil well metering. After selection and installation, 50 wells were fitted with HK-CMF mass flow meters and used and monitored for one year.
The results show that the measurement data of the oil well with the mass flow meter produced by Xiamen Hongkong has high accuracy and good stability, which can truly reflect the actual production of the oil well. At the same time, through the data transmission system, production management personnel can grasp the production of oil wells in real time and make production scheduling and decision-making. In addition, the use of mass flow meters simplifies the metering process, reduces manual handling and errors, and improves productivity.
IV. Conclusions. This article describes how mass flow meters work, their benefits, and application examples. The example shows that the mass flow meter has high accuracy and reliability in oilfield well metering, and can adapt to the needs of oilfield production. Therefore, it is recommended to promote the use of mass flowmeters in oilfield well metering to improve production efficiency and reduce production costs.
