The pore spaces are completely dominated by primary porosity and pores , vogs and fractures with secondary origination 孔隙空间主要是原生孔隙及由次生原因形成的孔隙和裂缝。
Rocks having original porosity are more uniform in their characteristics than those rocks in which a large part of the porosity is induced 具有原生孔隙度的岩石比次生孔隙度占大部分的岩石在性质上更具有一致性。
Original porosity is typified by the intergranular porosity of sandstones and the intercrystalline and oolitic porosity of some limestones 原生孔隙度以砂岩粒问孔隙度和某些石灰石的晶体粒间和鲕状孔隙度为代表。
The diagenesis of the ed3 and es , sandstone has been evoluted to late diagenesis a and b stage , with mainly primary pores and secondary solved pores 油气储层的储集空间以原生孔隙、次生溶解孔隙为主,主要为中孔中渗储层。
The formation mechanism of the pore of diagenetic dolostone includes : 1 ) the primary porosity is essential condition for the formation of dolostone reservoir 成岩白云岩孔隙的形成机制有: l )岩石的原生孔隙度是成岩白云岩储层形成的必要条件。
