Primary inter-granular pores and the enhanced inter-granular dissolution pores are reorganised as the most important pore spaces.
粒间原生孔和粒间溶蚀扩大孔是砂岩中极其重要的储集空间。
2
Through the pore structure analysis by capillary pressure curves, the type of the reservoir for the crack - dissolutionpore (hole) type;
并通过孔隙结构分析，按毛管压力曲线特征，将储层储集类型划分为裂缝-溶孔（洞）型；
3
The favorable reservoirs are dissolutionpore facies and chlorite cement facies in the sand bodies of subaqueous distributary channels and center of river mouth sandbars.
