查询词典 ursine seal

On the basis of study of fault seal history, together with the obtained achievement of structural stress field and fluid potential field, it is discovered that for the pool-forming process of oil and gas in the studied area the fault seal of nowadays is better than that of the Ed and Ng stages, it plays an important role to determine the oil column height and hydrocarbon preservation.

在断层封闭史研究的基础上，结合构造应力场及流体势场的研究成果，揭示了研究区油气的成藏过程，阐明了现今断层的封闭性优于Ed、Ng期断层的封堵性，并对油气的保存以及油柱高度的最终定型具有重要意义，而Ed、Ng期断层的封闭性对油气的分布态势有重要的影响。
