陆相断陷盆地三角洲相构形要素及其储层地质模型

THE ARCHITECTURAL ELEMENTS OF THE DELTAIC SYSTEM IN THE TERRESTRIAL FAULTED BASIN AND THE SIGNIFICANCE OF ITS RESERVOIR GEOLOGICAL MODEL

通过对我国东部断陷盆地现代和古代三角洲沉积体系的研究,系统地分析了三角洲的岩相及砂体的几何形态与成因,进而提出了陆相三角洲沉积的主要构形要素。由于构形要素分析是建立储层地质模型的关键内容,因此,笔者在所建立的储层地质模型上,分析了其结构类型特点及建立储层地质模型的真实内涵。

Through a study of modern and ancient deltaic depositional system in faulted basin of eastern China, the authors analysisze the geometry and genesis of sandbodies and lithofacies of deltas and proposed the main architectural elements of terrestrial deltaic deposits. As the analysis is the key content for a reservoir geological model, on the basis of the reservoir geological model of the deltaic system in the faulted basin of eastern China, the authors analysize the features of its structural types and true connotation of a reservoir geological model.
