摘要：

中扬子海相含油气区虽然经燕山构造运动的改造和破坏,但通过封盖和地下流体地化特征等保存条件的分析,在整体保存条件较差的背景中,存在有保存较好的区块,主要是凹中隆起区。据此提出。Ⅰ级有效保存区为沔阳、当阳区块,Ⅱ级较有效保存区为澧县区块,Ⅲ级可能保存区为长阳、潜江区块。

Abstract:

Though marine oil provinces in the Middle Yangzi Region underwent serious deformation due to Yenshan movement,and as a whole,the hydrocarbon preservation condition of theregion is poor,some blocks favourable for oil and gas preservation could be found within theregions according to the analysis of their sealing condition and geochemical property of subsurface fluid. It is proposed that Mianyang and Dangyang blocks should be considered as thefirst favorable ones,Lixian block could be taken as secondary favourable one, andChangyang,Qianjiang blocks might be the third ones.
