Temperature Factors Affecting the Error of Crude Oil Flow Meter

Abstract: The temperature factor information that affects the error of crude oil flow meter is provided by excellent flow meter and flow meter manufacturers. There are many reasons for the measurement error of the crude oil flowmeter. The literature has made its own analysis on the reasons for the error of the crude oil flowmeter. The main reason is that the properties of the oil measured are very different from the properties of the liquid used to calibrate the flow rate of the crude oil flowmeter. ,same. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the temperature factors that affect the error of crude oil flowmeters. There are many reasons for the measurement error of the crude oil flowmeter. The literature has made its own analysis on the reasons for the error of the crude oil flowmeter. The main reason is that the properties of the oil measured are very different from the properties of the liquid used to calibrate the flow rate of the crude oil flowmeter. At the same time, the temperature of the external environment will also affect the measurement accuracy of the flowmeter. There are many types of oil transported and metered in the Jingtang oil pipeline. The physical properties of the oil, especially the viscosity, vary greatly, and the viscosity has a great influence on the measurement accuracy. Moreover, the oil transportation task at this oil transportation place is heavy, and the oil transportation is switched frequently, so it is too late to calibrate each oil product. Therefore, when the properties of the oil products measured in the first and last two times are very different, or when the ambient temperature changes greatly, the crude oil flowmeter will have a large measurement error. Since the flowmeter at the oil delivery site has a large measurement error only when the oil product changes and the ambient temperature changes greatly, therefore, in such a short period of time, it is impossible for the crude oil flowmeter to have a similar wax deposition. A condition that takes a long time to establish adhesion to the inner wall. This paper selects representative oil products through experiments, compares the two factors of oil product viscosity and ambient temperature, and obtains the degree of influence of the two factors on the measurement accuracy of crude oil flowmeters. 1. Experimental method 1.1 Experimental content Establish a set of indoor loops to simulate the flow of on-site crude oil flowmeters to measure oil products. Control the oil temperature and the ambient temperature of the crude oil flowmeter, use the crude oil flowmeter to measure the oil flow under different oil temperature and ambient temperature, and compare it with the indication of the standard flowmeter. Using the method of multivariate analysis of variance in statistics, the two factors of oil viscosity and ambient temperature are analyzed by variance, and then the influence of oil viscosity and ambient temperature on the measurement error of crude oil flowmeter is studied. Finally, the main factors affecting the measurement results in oil measurement are obtained, and countermeasures are given. 1.2 Selection of experimental oil products There are many types of crude oil transported in this oil transportation site, and the properties vary greatly, mainly including the following: Jeno, Plutoni, Cabinda, Escider, Black Lion, Manji, Bonan , Mando, Oman, Shaqing, Urals, Ronkado, etc. When conducting experiments in the laboratory, through the comparison of crude oil properties, appropriate and representative crude oils are selected for experiments. Among the above types of oils, the wax precipitation points of the last five oils (Mandu, Oman, Shaqing, Urals, Ronkado) are between 15 and 20°C, and the freezing point is below -5°C, which is higher than the freezing point. Low; Black Lion, Manji, Bonan, the freezing point of these three types of oils is between 15 and 30 °C, the freezing point is higher, and generally prone to condensation accidents; Geno, Plutoni, Cabinda, Ace Heidel, the wax precipitation points of these four types of crude oils are between 25 and 30 °C, and the freezing points are all around 10 °C. In order to meet the requirements of the experiment and have sufficient contrast for different properties of crude oil, two kinds of Plutonian crude oil and sand light crude oil with large differences in properties were used as the experimental oil products for the experiment. Some physical parameters of the oil used in the experiment are shown in Table 1.

In order to simulate the on-site oil transportation process, the temperature of the oil product is adjusted by thermal resistance and cooling heat exchange tube, and the ambient temperature of the experimental crude oil flowmeter is adjusted by the constant temperature control device. The oil pump is pressurized and accelerated, and the oil flow speed in the pipeline is controlled by the circuit and valve 1, valve 2 and valve 3. During the experiment, control the oil flow rate and experiment temperature, and record the readings of the experimental crude oil flowmeter and the comparison standard flowmeter. (2) Test method First, the representative oil product of Plutoni selected in the experiment is used, and the influence of the oil temperature and the ambient temperature of the flowmeter on the measurement is compared through temperature control. The experimental method is as follows: Pour a sufficient amount of Plutoni oil into the oil tank, and turn on the oil pump to fill the entire ring. Turn on the heating resistor and agitator, and keep the oil temperature through the standard flow meter above the wax deposition point and a constant temperature through thermocouples, relays and other temperature control systems. Through room temperature control, the ambient temperature of the standard flowmeter is maintained at a higher temperature. Turn on the cooling device, cool the crude oil with a higher temperature to the experimental temperature by cooling the heat exchange tube, and then flow through the experimental crude oil flowmeter. At the same time, the constant low temperature water bath was turned on to control the ambient temperature of the experimental crude oil flowmeter.
