摘要
白音查干凹陷特殊岩性段作为层序划分的意义在于它出现在层序内最大水泛面和水进体系域上部的转折点,是可容纳空间持续增长、增长速率变小直至不再增长的特定时间段的产物。其特殊的岩性及电性特征可以作为全盆地范围进行等时追踪对比的标志。特殊的岩石组合反映停滞封闭的静水环境,在白音查于凹陷代表半深湖沉积。
The significance of sequence classification of special lithologic section in Baiyinchagan Sag is that within the sequence there exists a maximum waterflooding surface and a transfer point at the upper part of water transgressive system, which is the result of a special time interval that the accommodation space continuously increases, but its rate decreases until it doesn't increase any more. Its special lithologic and resistive characteristics are the marks of tracing and contrasting i-sochronously in the whole basin. The special rock assemblage reflects the closed standing water circumstances, and it represent hemi-deep lake deposition in Baiyinchagan Sag.
