Deformation Superimposition Characteristics Resulting from Stretching Direction Changes in Nanpu Sag:Insight from Physical Modeling
摘要
Abstract
According to the comparison of the previous modeling results and the actual geological conditions in Nanpu sag,different series of physical models which are in different stretching directions and different pre-exist-ing basin structures have been conducted.Furthermore,the Cenozoic fault systems in Nanpu sag are discussed. The results can be concluded as follows:(1 )The Cenozoic fault systems in Nanpu sag are the result of two-phase extensions with different stretching directions. (2 )The NE-SW fault systems had undergone NW-SE extension during the Shahejie depositional period;while the EW fault systems had undergone SN extension since Dongying depositional period.The early Dongying period witnessed the changes of regional stress direction of Nanpu sag.(3 )The structural characteristics in different depositional periods were controlled by particular boundary geometry,basal heterogeneity,and distribution of pre-existing faults.关键词
