根据大量的岩石薄片、X衍射、地球化学等测试资料,对辽河坳陷辽中凹陷成岩作用及孔隙演化进行了详细研究,并在此基础上划分了5个成岩阶段:早成岩A期、早成岩B期、晚成岩A期、晚成岩B期和晚成岩C期。
In the north, the reservoir rocks are mainly sandstones and conglomerates that entered the later diagenesis earlier at the shallower depth.
东营凹陷可分为北部陡坡带、中央隆起带和南部缓坡带 ,由于地质背景有差异 ,古近系砂岩储集层在不同地区的特征不同 :北部陡坡带以近岸水下扇砂砾岩沉积为主 ,进入晚成岩期的时间早 ,深度浅 ,次生孔隙发育中等 ,主要分布在 165 0～ 2 45 0m深度 ,3 2 0 0～ 3 5 0 0m深度存在第二次生孔隙带 ,碳酸盐溶蚀和胶结作用在垂向具有分带性 ;中央隆起带以浊积扇砂岩为主 ,但由于断裂发育 ,酸性水活跃 ,进入晚成岩期的时间也较早 ,次生孔隙最发育 ,且分布范围大 ,180 0～ 3 5 0 0m深度均发育次生孔隙 ,碳酸盐胶结弱 ,储集层物性最好 ;南部缓坡带以滨浅湖和三角洲沉积为主 ,进入晚成岩期的时间晚 ,次生孔隙发育少 ,北部和中部物性相对差。
