Abstract: In order to make sure the hydrocarbon source and migration path of N22 in the Nanyishan oilfield, we use the technique of reservoir geochemistry and the correlation principle of statistics to filter and analyze the migration indexes, by combing several kinds of indexes we make a conclusion that there are two oil and gas inject directions (northwest and northnorthwest) in the research area, indicating that the oil and gas are from Xiaoliangshan depression, which is consistent with the result of the oil sources comparative study. And the research find that nitrogen compounds, which serve as the tracers for oil and gas migration, have feasibility and advantage to some extent.
