摘要
The Permian sandy conglomerates in Kebai area is one of the most important petroleum reservoir rocks in Junggar Basin. In this paper, the type of rock and the diagenesis of Permian sandy conglomerates in the study area is studied. It suggests that the factors of influencing reservoir property in the study area are compaction, cementation and dissolution. In terms of the research on stage and characteristics of diagenesis, the Permian sandy conglomerate reservoirs in the study area are divided into seven diagenetic facies. Then, the conditions of diagenesis facies, the feature of diagenesis, the environment of diagenesis, model of diagenesis and evolutionary sequence of diagenesis are concluded and summarized.
