摘要:
目前国内还缺乏有效的气相色谱方法来测定原油全烃碳数分布，主要受制于不能气化的重组分滞留于色谱仪进样口，实验图谱中能出峰的是部分较轻组分，归一法计算只能得到较轻组分的质量比例关系，而大型油藏数值模拟软件对油气组分要求越来越高。为突破此技术瓶颈，首次提出二次平行进样方法，实验出峰各结果用内标差值法计算出重组分质量含量，并通过编制计算软件处理数据，成功实现了未气化组分含量测量。实验结果通过和瑞士SGS标准分析室验证确认了准确性，本方法符合国际GPA 2186标准，且在其基础上对重组分分析做了改进，延伸了对原油全烃碳数分布规律的认识，提高了油藏数值模拟精度和油气田开发方案编制水平。
Abstract:
At present，there is still a lack of effective gas chromatography method to determine the total carbon number distribution of crude oil in China.It is mainly restricted by the heavy composition that can not be gasified remaining in the inlet and the peaks shown by only some of the lighter composition.The normalization method can only obtain the weight ratio of lighter compositions， but the numerical simulation software for large reservoirs has increasingly higher requirements for oil and gas composition.In order to break through this technical bottleneck，a second parallel injection method was proposed for the first time，and the results were used to calculate the mass content of heavy composition by using the internal standard difference method，and the data were compiled by processing calculation software to successfully achieve the measurement of ungasified composition content.The results were verified by the Swiss SGS standard analysis laboratory，which confirmed the accuracy.This method complies with the international GPA 2186 standard. On the basis of this method，the heavy composition analysis method has been improved，the understanding of the distribution law of the total carbon number in crude oil has been extended，the numerical simulation accuracy of reservoirs and the level of development plans for oil and gas fields have been enhanced.
