柴达木盆地南翼山油田的油气充注成藏途径

为了确定南翼山油田浅层(N22)的油气来源和油气的运移路径，利用油藏地球化学技术和统计学上的相关性原理进行运移参数的筛选和分析，综合各项指标认为，研究区的油气在西北和北北东各有一个注入方向，说明油气主要来自北边的小梁山凹陷，这与油源对比的结果相符。研究表明，含氮化合物作为油气运移的示踪剂具有一定的可行性和优越性。

The Path of Hydrocarbon Charge and Accumulation in Nanyishan Oilfield of the Northwest Qaidam Basin

In order to make sure the hydrocarbon source and migration path of N22 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 north north west) 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.
