| 摘 要： | 通过对墨西哥湾不同时代可采储量的分布特征和油源对比资料的分析认为,晚侏罗纪烃源岩是墨西哥湾南部最主要的烃源岩。资料显示,晚侏罗纪优质烃源岩形成的主控因素是稳定的构造和沉积条件以及超咸的还原环境,其中,"世界顶级"的晚侏罗纪提塘阶烃源岩主要形成于超咸的碳酸盐岩和/或蒸发岩沉积环境,属半深海还原环境,有机质以藻类为主,推测烃源岩中的有机质可能与极端干旱气候条件下的藻类勃发有关。

| Abstract: | On base of the summary of the distribution of proved reserves from different ages and the correlation between oil and source rocks in the Gulf of Mexico,it is concluded that Upper Jurassic source rocks are the best ones in the region.The data show that the main controlling factors of Upper Jurassic source rocks are stable tectonics and hyper saline/reducing environments.Among them,Upper Jurassic source rocks mainly formed in the hyper saline carbonate evaporite sedimentary environment,belonging to hemi-pela... |
