《石油计量表》中原油计量应用软件的设计与制作

Design and Development of Crude Oil Measurement Application Software for “Oil Measurement Meter”

通过查阅文献后利用迭代公式,总结出GB/T 1885—1998《石油计量表》中标准密度和体积修正系数的计算流程,建立迭代函数和数字修约函数,得到简便的Excel表格。因此,通过编制软件计算成为可能,且更为精确。其中,该软件计算原理及方法在Excel和Android环境下已实现,与人工查表相比,数据准确可靠。国内外同行业软件计算结果的误差率在0.1‰~4‰,该软件计算结果的误差率仅为0.1‰。

By consulting the literature and using the iterative formula, this paper summarizes the calculation process of the standard density and volume correction coefficient of crude oil in GB/T 1885—1998“Oil Measurement Meter”, establishes the iterative function and digital rounding function, and obtains the portable Excel table. Therefore, it is possible and more accurate to calculate the standard density and volume correction factor of crude oil by compiling software. The calculation principle and method of the software have been realized in Excel and Android environment. Compared with manual table lookup, the calculation data is more accurate and reliable. The error rate of the calculation results of similar softwares at home and abroad is 0.1 ‰ ~ 4.0 ‰, while the error rate of the calculation results of this software is only 0.1‰.
