摘要
根据扬子地区地质和油气的特殊性,提出下扬子地区海相地层可依据二级层序开展盆地分析、层序地层研究和含油气系统的分析,以恢复二级层序的古面貌。重要的是了解上覆二级层序的地质事件对下伏二级层序的改造作用,以认清改造后的新平衡(物理场、应力场、化学场、温度场、含油气系统),建立符合实际的地质模型。
Based on the particularity of the geology and hydrocar- bons in the Yangtze region and the new development of petroleum geology and the geoscience,it is suggested that basin analysis,research of sequential stratigraphy and petroleum system analysis on marine strata of Lower Yangtze should be carried out with respect to second order sequences on purpose to restore the paleostatus of the sec- ond order sequences.Besides,it is important to find out what the effect of the geologic events of the overlying second or- der sequence is to the underlying second order sequence.At last we'll get clear understanding to the new balance after reformation (physical field,stress field,chemical equilibri- um,thermal field,petroleum system),and set up a realistic geological model.
