primary porosity

基本解释

Primary porosity is the main pore type in sandstone reservoir.
砂岩储层的孔隙类型以原生孔隙为主。
Porosity evolution in the rock has experienced destruction of primary porosity and construction and then re-destruction of secondary porosity.
孔隙演化经历了原生孔隙的破坏、次生孔隙的形成和次生孔隙的破坏三个阶段。
The study of porosity evolution shows the compaction is the main cause resulting in the disappearance of primary porosity, and the next one is cementation.
通过孔隙演化研究发现，压实作用是该区原始孔隙损失的最主要因素；其次为胶结作用。
