中长期基准面变化过程中可容纳空间的变化,对含油气盆地沉积体系的形成与分布具有明显的控制作用,从而控制着油气的生储盖组合及岩性油气藏的特征及类型。本文作者根据吐哈盆地台北凹陷侏罗系中长期基准面的变化,总结出基准面变化过程中油气的生储盖发育分布规律,及其岩性油气藏的类型、特征和发育分布规律,对吐哈油田岩性油气藏的勘探具有一定的指导意义。
The change of accommodation space in mid- and long-term datum changes obviously controls the formation and distribution of sedimentary systems in the petroliferous basins, and thus controls the characteristics and types of reservoirs and caprock assemblages and lithologic reservoirs. Based on the changes of the Middle and Long-term datum of the Jurassic in the Taibei Sag, Turpan-Hami Basin, the authors summarize the development and distribution rules of the reservoirs and reservoirs in the process of datum change and the types, characteristics and development and distribution of the lithologic reservoirs. Exploration of lithologic reservoirs in Tuha Oilfield has certain guiding significance.
