摘要
经典的石油生成理论认为凝析油是源岩高成熟阶段、或是陆相有机质于低成熟阶段的直接产物。本文在资料、数据分析的基础上结合我国塔北海相油田的实际地质地化资料提出原油蒸发分馏机制是凝析油形成的一种重要途径，并确认了塔北油田的诸多原油曾遭受了程度不一的蒸发分馏作用且有成熟度正常的凝析油形成。
According to the viewpoint of the conventional theory,the condensates are generallythe direct products of source rocks at the higher maturation levels or terrestrial organicmatter at the lower maturation levels. The result of this study suggests that the petroleumevaporative fractionation is a significant mechanism for the generation of condensate,andmeanwhile the fractionated crude oils and the evaporative condensates with normal maturi-ty by this way were also recognized in Tarim basin.
