摘要
济阳坳陷新近系馆陶组储层具有低成分成熟度、较低结构成熟度的特点;馆陶组各段储集岩的自生矿物,主要是各种自生黏土矿物和碳酸盐矿物,此外还有自生的黄铁矿、石英等;馆陶组储层处于早成岩期的A阶段;砂岩的储集空间有原生粒间孔、裂隙、解理缝、溶蚀孔、微孔隙等。
The compositional and textural maturities are low in the reservoir rock of Guantao formation in Jiyang Depression.The authigenic minerals are mainly composed of authigenic clay minerals and carbonate minerals.It is at a stage of early diagenesis.There are primary intergranular pores,fractures,cleavage fractures,dissolution pores and micropores in the reservoir space of sandstone.
