摘要
根据包体的组成和荧光性将包体组合分为三种类型,为油气运移史提供了有用的参数。研究表明:当深3井的海相地层有过三次不同阶段的油气运移;印支运动和早、晚期燕山运动形成的裂缝为油气运移提供了通道;当深3井的海相地层中未发生过较大规模的油气聚集,其中的碳酸气是在早第三纪聚集成藏的。
Based on inclusion composition and fluorescent characteristics, inclusions are classified into three types, which would serve as useful parameters in the petroleum migretion studies. It is shown that there are three different evolutional stages of petroleum migration for the marine strata in the well Dang- shen 3, fractures formed during the Indosinian and the early and late Yanshan movements would provide pathways for petroleum migration, and no large-size petroleum accumulation has occured within the ma- rine strata of the well Dangshen 3, in which, the carbon dioxide was accumulated dring the Eogene.
