中文摘要：

对准噶尔盆地腹部达巴松凸起白垩系油气显示进行地质与（有机和无机）地球化学综合研究,分析其所反映的油气运聚类型,进而讨论成藏主控因素,为区域油气勘探提供信息。结果表明：达巴松凸起白垩系油气有过运移但未成藏,其主要原因依次为油气充注不足和圈闭空间不足;在油气优势运移方向上的储层和有断裂沟通油源的圈闭将成为下一步的区域油气成藏研究和勘探的重点;通过分析油气运聚类型来研究成藏主控因素的方法得出的认识更为具体,可用来帮助查明油气成藏的主控因素。

英文摘要：

Geological and organic-inorganic geochemical feautres were investigated for hydrocarbon show in Cretaceous of Dabasong uplift of central Junggar Basin.On the basis of the features,the petroleum migration and accumulation type was analyzed,which in turn implies the controlling factor of petroleum migration and accumulation and provides valuable information for shaping petroleum exploration strategies.The results show that petroleum has migrated,whereas not accumulated in the Dabasong uplift.The main reasons are deficiency of hydrocarbon charging intensity and unfavorable trap conditions.Therefore,oil and gas intervals can be formed and discovered if the reservoir is placed in the hydrocarbon migration conduit system and faults connect oil-source sags and traps.This new understanding was obtained by using a new method of addressing the controlling factor of petroleum migration and accumulation by analyzing its type,which can be used to identify the controlling factor of petroleum migration and accumulation.
