摘　　要：百色盆地田东凹陷子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 carbonate and silica cementation are two main types of diagenesies in the sandstone reservoir Nadu formation,Ziyin oil field .Tiandong Depression,Baise Basin. They occured in different di-agenesis stages and geochemical conditions,controlled by organic acid generated from the mudstone during organic evolution. They take important part in the forming and developing of the reservoir pores.
