异构烷烃分析及在石油地质研究中的应用

简要介绍了展构烷烃分析技术。利用热解气相色谱分析方法，依据担体物理性质和被测物化学结构特点，优选出最佳担体，保证了异构烷烃分析精度，从而使异构烷烃分析能够直接从烃源岩、储集岩、饮和烃等样品难过热蒸发分离进行检测。降低分流比，增加进样量，提高灵敏度，使常量分析提高到痕量分析。对异构烷烃化合物在石油地质方面的应用进行了初步探讨。

ISOPARAFFIN ANALYSIS AND ITS APPLICATION IN PETROLEUM GEOLOGY

This paper gives an introduction to the technique of isoparaffin analysis. It uses pyrolysis gas chromatography analysis method, based on carrier physical properties and the chemical structure of tested matters, to optimize the best carrier in order to ensure the accuracy of isoparaffin analysis. This makes isoparaffin analysis pass thermo vaporation separation examination from the sample of hydrocarbon source rock, reservoir rock and saturated hydrocarbon. It decreases the fractional flow ratio, increases sample injection rate and sensitivity, so as to improve macro-analysis to trace analysis. This paper discusses the application of isoparaffin compound in petroleum geology.
