摘要
本文较系统地讨论辽东湾下第三系砂岩成岩特征，分析五种主要的成岩作用，并综合多种成岩标志，划分出四个成岩阶段，同时探讨成岩作用对砂岩储集性的影响。根据成岩机理与油气分布关系的分析，提出成熟阶段A是有利的成岩带；三角洲分流河道、水下河道、河口坝，以及水下扇辫状水道是有利的沉积相带。将二者叠合，预测了有利的储集区带。
Diagenetic characteristics of Eogene sandstones in Liaodong Bay have been discussed systematically in this paper.According to five main diagenesis analysis and many diagenetic markers,four diagenetic stages (immature stage,semi-mature stage,mature stage A,mature stage B) have been divided.In addition,the control of diagenesis on reservoir quality has been studied.Base on the analyse of relation of diagenetic mechanism and hydrocarbon distribution,mature stage A has been considered good diagenetic zone and dis- tributary channel,river mouth bar,braided channel have been considered good sedimentary facies zone. Overlaying above mentioned areas of the two zones have predicted the favourable reservoir zone.
