摘要：

下扬子地区寒武系的白云石化作用、埋藏溶蚀作用及差异压实作用,是形成有利储集空间的重要成岩作用,形成裂缝-孔隙型硅质岩、微晶灰(白云)岩、裂缝型泥岩、微裂缝-缝合线型泥质灰岩和碎屑流砾屑灰岩、浊积岩等多种储集空间,构成斜坡带油气聚集的有利条件.

关键词: 寒武纪, 斜坡－盆地相, 成岩作用, 储集类型

Abstract:

Dolomization, burial dissolution and differential compaction in Cambrian of Lower Yangtse Region are important diagenesis in forming such favourable reservoir rocks as fracture-porous siliceous rocks, micrite (microcrystal dolomite), fissured mudstone,fissure-sutured argillaceous limestone, calcirudite. and turbidite, which then constitute slope reservoir zones in the region.
