通过对塔河油田奥陶系油气地球化学特征与油气运移关系的研究,认为:a)油气物理性质可以宏观地反映油气运移的方向;b)原油轻烃、生物标记物和含氮化合物可以较好地反映油气运移方向,饱和烃生物标记化合物反映了相对轻质原油的油气运移方向,含氮化合物则主要反映了相对早期原油的运移方向;c)塔河油区存在着早期由南向北、晚期由南向北、由东向西的油气运移充注过程.

Based on study of relationship between petroleum geochemistry and hydrocarbon migration of the Ordovician oil in Tahe oilfield of the Tarim basin,it was indicated that:a)the physical properties of oil and gas may macroscopically show direction of hydrocarbon migration;b)light hydrocarbon,biomarker and nitrogenous compounds of crude oil can better reflect direction of oil gas migration,i.e.biomark compound of saturated hydrocarbon represents migration direction of relative light oil and nitrogenous compounds are indicator of relative early migration;c)direction of hydrocarbon migration was from south to north in the early stage but it migrated both from south to north and from east to west in the late in Tahe oilfield.
