百色盆地田东凹陷于寅油田那读组砂岩储层中.碳酸盐胶结作用和硅质胶结作用是两个极重要的成岩作用、它们受泥岩中有机质演化形成的有机酸的影响和控制,分别形成于不同的成岩阶段和不同地化环境.它们对储集岩中孔隙的形成、发育具有重要意义. The Tiandong depression in the Baise basin is a sandstone reservoir in the Nanyan Formation of Yin oilfield.Carbonate cementation and siliceous cementation are two very important diagenetic processes that are influenced and controlled by the organic acids formed by the evolution of organic matter in the mudstone, They are formed in different diagenetic stages and in different environments, which are of great significance to the formation and development of the pores in the reservoir rocks.
