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.展开更多

文摘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.
