摘要
辽河断陷的早第三纪湖盆属于小型断陷湖盆,其中扇三角洲沉积分布广,发育时间长。本文对沉积相标志和沉积机理进行了系统研究,对扇三角洲沉积的概念、特征和模式进行了论证。按其水动力特点,采用粒度概率曲线分类统计法,对其中的十二个扇三角洲沉积体进行了定量成因分类,划分了六种沉积类型。分类结果不但符合盆地区域构造和沉积发育的时空规律,而且深刻揭示了各类扇三角洲储层非均质特征参数间以及开采特点之间的规律性。由此而建立的系统分类模式,可以作为勘探开发早期对扇三角洲储层进行类比的标准和预测的模式。
There are many types of fan deltas in a wide range and have different properties in the continental lacustrine basin of Paleogene System in Liaohe faulted basin. The origon of 12 fan delta reservoirs is quantitatively classified by means of the classification according to the statistics of grain size probability curves. Based on the development characteristics of the faulted basin, facies model, sedimentation hydrodynamics and the results of lithofacies analysis six types of sedimentation are divided, three heterogeneity patterns are summarized and the pricipal formation parameters for each type of reservoir are obtained.
