In the present paper is recommended a new method of directly injecting crude oil into a gas chromatograph for gas chromatographic analysis, which has been proved valid it the analysis and investigation of crude oil samples from different formationsin China. In terms of the distribution patterns of hydrocarbons in “total hydrocarbon”chromatogram and the relative values of their major characteristic peaks,types of crude oil of different forations from a same region can be readily recognized and a comparison of different oil sourees can also be made.Meanwhile,it might be adopted to eveluate the geological conditions in favour of oil preservation. 相似文献

洱海是我国云贵高原上的一个内陆断陷型淡水外泄湖,南北长42.6km,东西最宽为8.2km,面积约250km~2,最大水深20.7m。弥苴河为该潮的主要水源,西洱河为唯一出口。洱海属温暖气候,湖水为中等营养类型。它是一个研究现代沉积物有机地球化学较理想的湖泊。近代沉积物是地质历史发展的最新一页。它虽然不是地质历史的重演,但通过对它的研究,仍可追溯地质发展过程中曾经发生过的某些自然现象。对湖泊沉积物有机地球化学的研究,可以加深人们对原始有机质特征以及在早期生物化学作用下演化趋势的认识。 相似文献
