Xiamen Hongkong Instrument Engineer will explain to you: the application of mass flow meter in the liquid production measurement of heavy oil block in oilfield.
With the deepening of oilfield development, the production of heavy oil blocks occupies an increasingly important position. However, heavy oil has the characteristics of high viscosity, high density and poor fluidity, which brings great difficulties to the measurement of liquid production. Traditional volumetric or turbine flowmeters are easily affected by factors such as viscosity, density and sand content of heavy oil when measuring heavy oil, and the measurement accuracy is difficult to guarantee. Therefore, it has become an urgent need to find a flowmeter suitable for heavy oil metering. As a flowmeter based on the weighing principle, the mass flow meter has the advantages of high measurement accuracy, good stability and wide application range, and has gradually been applied in the measurement of liquid production in heavy oil blocks in oilfields.
The application advantages of mass flowmeter in the measurement of liquid production in heavy oil blocks of oilfield are mainly reflected in the following aspects:
1.High measurement accuracy: The mass flow meter adopts the weighing principle to directly measure the mass flow of liquids, which is not affected by viscosity, density and other factors, so it has high measurement accuracy.
2.Good stability: the mass flow meter has a simple structure, few moving parts, easy maintenance, and can operate stably for a long time.
3.Wide range of application: Mass flow meter can be used for various types of heavy oil, including high viscosity, high density, high sand content, and has a wide range of applications.
4.High degree of automation: The mass flow meter can be integrated with the automatic control system to achieve remote monitoring and data collection, and improve the measurement efficiency and automation level.
However, there are also some difficulties and challenges in the application of mass flow meter in the measurement of liquid production in heavy oil blocks in oilfields. First of all, heavy oil has high viscosity and large sand content, which is easy to form blockage and wear inside the flowmeter, and effective anti-blocking and anti-wear measures need to be taken. Secondly, due to the high density of heavy oil and the large change of moisture content, it is necessary to compensate the density and moisture of the mass flow meter to ensure the measurement accuracy. In addition, it is also necessary to select the appropriate mass flow meter model and specification according to the specific situation of the oilfield, and carry out installation, commissioning and daily maintenance work.
In response to these difficulties and challenges, the following measures can be taken:
1.Select the appropriate mass flowmeter model and specification: According to the actual situation of the heavy oil block in the oilfield, select the appropriate flowmeter model and specification to ensure that the flowmeter has sufficient measurement accuracy, stability and durability.
2.Optimize the installation method: In view of the problem that heavy oil is easy to block and wear, suitable installation methods can be adopted, such as installing filters, adjusting the installation angle, etc., to reduce the occurrence of blockage and wear.
3.Density and moisture compensation: In view of the characteristics of heavy oil with high density and large change in moisture content, density and moisture compensation can be carried out in the mass flow meter to improve the measurement accuracy.
4.Strengthen daily maintenance: regularly inspect, clean and maintain the mass flow meter to ensure its long-term stable operation.
5.Improve the level of automation: Adopt advanced automation technology, such as remote monitoring, data collection and analysis, etc., to improve the measurement efficiency and automation level.
In summary, the mass flow meter has a broad application prospect in the measurement of liquid production in heavy oil blocks in oilfields. By taking appropriate measures to solve the existing difficulties and challenges, we can give full play to the advantages of mass flow meters, improve the accuracy and reliability of heavy oil measurement, and provide a strong guarantee for the stable production and economic efficiency of the oilfield.
