摘要： 总结了塔中隆起石炭系CⅠ 油组石英砂岩储集层的压实、压溶、胶结、溶解、交代作用等成岩特征, 划分出准同生期、早成岩A 期和B 期、晚成岩A 期和B 期五个成岩阶段, 通过成岩机理的分析, 提出本区成岩环境是一个半封闭到封闭的系统, 建立了成岩模式,并讨论了成岩作用的影响因素及其与储集性能的关系。

Abstract: This paper summarized the diagenetic features of CⅠ oil group quartzose sandstone reservoir of Carboniferous system in Tazhong uplift, such as compaction and pressure solution, cementation, dissolution, alteration and replacement.Five stages of diagenesis were classified, including penecontemporaneous, early diagenetic stage A and B, late diagenetic stage A and telo diagenetic stage B.By analysis of the diagenetic mechanisms, furthermore, diagenetic mode is established.For the first time, it is pointed out that the diagenetic environment in this region was a semi-sealed to sealed system. Factors affecting the diagenesis and their relations to reservoir quality of CⅠ oil group are discussed.
