本文报告用红宝石激光裂解气相色谱法(简称LPGC方法)对岩样内芳香烃丰度的研究结果.实验数据指出岩样内芳香烃的丰度,可由激光裂解产物中C_2H_2的相对丰度来确定.从而提供了一种快速而又简便地判断沉积岩中生油岩的LPGC方法.同时还从等离子多化学反应过程的观点,对激光裂解机理等有关问题作了初步的理论分析.
In this paper, we report the results of ruby laser pyrolysis gas chromatography (referred to as LPGC method) on the abundance of aromatic hydrocarbons in rock samples.The experimental data indicate that the abundance of aromatic hydrocarbons in rock samples can be determined by the relative abundance of C_2H_2 in the laser pyrolysis products Thus providing a quick and easy method to determine the LPGC of source rock in sedimentary rocks.At the same time, from the point of view of plasma chemical reaction process, some preliminary theoretical analyzes on the laser pyrolysis mechanism and other related issues were also made.
