论述了四川盆地灯影组储层段内亮晶颗粒白云岩和蓝菌藻粘连白云岩中胶结物的发育情况:颗粒和蓝菌藻粘结组构间的原始孔隙在四期七种不同结构类型的白云石胶结物充填后基本消失;形成于不同成岩环境中的白云石胶结物,在产状、矿物学和地球化学等特征上虽有较大的差异,但总体又具有一定的变化趋势,即随埋藏深度的增加,胶结物在由孔隙边缘向中心充填的同时,晶粒变粗、颜色变浅、包裹体增多、温度升高、同位素值偏负、阴极发光强度变强。
The development of cements in Liangding granulite dolomite and cyanobacteria algae cementation dolomite in Dengying Formation reservoir section of Sichuan Basin was discussed. The original pores between the cements and the blue algae cements were found in four stages of four different structural types Of the dolomite cements were almost completely disappeared. Although the dolomite cements formed in different diagenetic environments have great differences in their occurrences, mineralogical and geochemical characteristics, they generally have a certain trend of change, That is to say, with the increase of burial depth, the cements fill in from the edge of the pores to the center, while the grains become coarse, the color becomes lighter, the inclusions increase, the temperature increases, the isotopic value is negative and the cathodoluminescence intensity becomes stronger.
