岩石吸留烃气相色谱快速检测技术及其应用研究

在油气勘探有机地化实验室中 ,岩石中全烃制备分析方法主要有“岩石氯仿抽提物及气相色谱分析技术”、“岩石热解气相色谱分析技术”等 ,而这些技术都存在操作烦琐、不适合钻井现场分析等缺陷 ,而新开发的岩石吸留烃气相色谱快速检测技术 ,就是利用气相色谱仪特点研制出解吸装置及技术 ,省去了实验室中繁杂的烃类制备过程 ,直接进岩样测定岩石中吸留烃C3—C4 0单体烃化合物。本方法不仅适合实验室岩石中全烃分析 ,更适合现场分析 ,在柴达木盆地某深探井现场地化录井及识别真假油显示的实际应用效果好 ,是油气地球化学勘探的一种新方法。

QUICK GAS CHROMATOGRAPHY ANALYSIS TECHNOLOGY OF THE ADSORBED HYDROCABON IN ROCKS AND ITS APPLICATIONS

In the organic geochemistry laboratory, the methods of preparating and analyzing bulk hydrocarbons in rocks are mainly the “chloroform bitumen “A” of source rock and gas chromatography analysis technology”, the “pyrolysis chromatography analysis technology”, etc. As these analysis technologies are very trouble some in operation, it does not fit to field analysis. We have developed a new method——“quick gas chromatography analysis technology” to analyze adsorbed hydrocarbons, using the gas chromatography instrument. The technology can leave out the annoying preparation process and determine the C3—C40 single hydrocarbons. The new technology is not only applicable to analysis of bulk hydrocarbons in the laboratory, but also to field analysis. The chromatography logging result for a deep prospecting well is good in the Qaidam Basin, and the effect of identifying the real or false oil is good, too. The analysis technology is a new method in petroleum exploration.
