摘要:

结合前人研究成果和当前的研究现状,探讨了基准面和可容空间的影响因素及作用方式,指出可容空间的变化存在绝对可容空间和相对可容空间两种情况,沉积物供应不是影响基准面变化的因素。总结了短期基准面旋回在纵向上的叠加方式,指出了其在横向上的变化特征。提出了以基准面旋回研究为基础,依据古地形变化进行有利储层预测的研究思路。

Abstract:

Based on previous study,this article discussed factors and patterns that influence the base-level and accommodation.It concluded that both Absolute and relative accommodation changes exist and that the sediment supply isn't a factor influencing the change of base-level.It also studied the vertical superimposing patterns and lateral variations of short term base-level cycles and advanced the approach of predicting favorable reservoirs according to change of paleotopography based on the analysis of base-level cycles.

Key words: base-level, accommodation, paleotopography, high-resolution sequence stratigraphy, faulted lacustrine basin
