摘要
本文以青海省油砂山露头研究为例，从5个方面不同层次阐明了定量储层沉积学是获取储层建模地质信息的重要途径：（1）沉积体系和做相分析是认识储层宏观特征的基础；（2）通过砂体测量，掌握砂体大小、几何形态、展布方向及内部非均质性；（3）镶嵌照片与密集柱状剖面相结合以确定破体的连通性和面积比；（4）各类砂体的发育程度及其物性分析为储层评价提供依据；（5）成岩作用和孔隙结构研究揭示储层做现非均质性。
Taking the study on the outcrop of Youshashan in Qinghai Province for example, this paper expounds from five aspects in different level that Quantitative Reservoir Sedimentology is an important way to obtain geological information for reservoir model establishment: (1) the sedimentary system and microfacies analyses are the bases for understanding the macrofeature of reservoirs; (2)the size, geometry, orientation and internal anisotropism of sand body are known by sand body measurement; (3)the connexion and area ratio of sand body can be determined by mosaic photoes combined with close columnar sections; (4) the analyses on the development stage of each type of sand body and its lithology provide bases for reservoir evaluation; and (5) the study of diagenesis and pore structure reveals the microanisotropism of reservoirs.
