| 摘 要： | 通过分析埕岛东斜坡地区东三段砂岩成岩作用特征 ,以及对该地区油气成藏系统的研究 ,总结出东三段砂岩体的成岩成藏模式。东三段上部砂体成藏于馆陶组沉积期 ,对应于早成岩 B期阶段 ,油气过早进入砂岩体 ,充填了孔隙 ,抑制了成岩作用的进行 ,使原生孔隙得以良好的保存。目前该砂体位于晚成岩 A期阶段 ,伴随形成了次生孔隙 ,并正处于第二次成藏期

| Abstract: | Based on the study of diagenetic characteristics and petroleum system, this paper has summarized the diagenesis pool forming model of the lower member of Dongying Formation (Dong 3 member) in the eastern slope area of Chengdao. The upper sandbody of the Dong 3 member formed reservoir during the subatage B of the early diagenetic stage (Guantao Formation).The early filling of oil and gas in the pore of sandstone restrained the diagenesis and preserved the primary pore.Now the sand body is in the late diagenetic stage A and associated with secondary pore,and is in the second pool formation period. |
