【摘要】 在石油密度测试实验中,测试得到的油品视密度需要查表换算为20℃时的标准密度,该过程繁杂、效率低。通过提出适合原油、石油产品、润滑油的视密度与标准密度之间的换算公式,可以直接一步计算得出标准密度,方便简单、计算精度高、适用范围广,为利用计算机辅助进行石油标准密度的转换提供了基础。通过教学实践证明利用换算公式可以大幅提高石油标准密度的计算效率,特别适用于大量石油密度测试数据的分析与处理。更多还原

【Abstract】 In the petroleum density measurement experiment,the apparent density of petroleum needs to be converted to the standard density at 20 ℃ by look-up table. The conversion process is complicated and inefficient. A conversion formula is proposed for crude oil,petroleum products and lubricating oil. This formula can simply calculate the standard density in one step with high calculation accuracy and wide application range. It provides the basis for computerassisted conversion of petroleum standard density. It can be proved that the formula can improve the calculation efficiency of petroleum standard density by teaching practice and it is also suitable for a large number of oil density test data processing.更多还原
