碳酸盐岩孔隙演化受各种成岩作用的控制，其中胶结作用对孔隙演化起了重要的作用。利用地球化学分析手段，对川东石炭系碳酸盐岩胶结物进行了研究，碳酸盐岩中存在白云岩粒间胶结和石灰岩粒间胶结两种胶结物，不同成岩时期及成岩环境形成的胶结物的地球化学特征差异显著。川东石炭系埋藏成岩作用过程中，埋藏胶结物对孔隙演化有一定的影响。利用地球化学手段定量地描述胶结作用，为预测有利勘探目标提供了理论依据 Carbonate pore evolution is controlled by various diagenetic processes, in which cementation plays an important role in the evolution of porosity. Using geochemical analysis, the carbonate cements in eastern Sichuan were studied. There are two types of cements: dolomite intergranular cementation and limestone intergranular cementation, which are formed in different diagenetic stages and diagenetic environments The geochemical characteristics of cement are significantly different. During the process of burial diagenesis in the Carboniferous of eastern Sichuan, the burial cementation has some influence on the pore evolution. Using geochemical means to quantitatively describe the cementation provides a theoretical basis for predicting favorable exploration targets
