【摘要】 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.更多还原

【Abstract】 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.更多还原
